| 2 | Visible light-induced N-doped TiO_2 nanoparticles for the degradation of microcystin-LR显示文摘N-doped nano-crystalline TiO2 powders have been synthesized by the sol-gel method.The shape and crystal structure of the resulting N-doped TiO2 were investigated by X-ray Photoelectron Spectroscopy (XPS),X-ray spectroscopy (XRD),Transmission Electron Microscopy (TEM) and UV-vis reflection spectrum.The results showed that doping TiO2 with nitrogen can lower its band gap and apparently shift its optical response to the visible region.Under the visible light (λ> 420 nm) irradiation,the MC-LR was degraded by the synthesized N-TiO2 nano-material.The variation of MC-LR amount and its intermediates were detected by high performance liquid chromatography (HPLC) and LC-MS,respectively.The mineralization of MC-LR was determined by total organic carbon (TOC) analysis.Simultaneously,transient oxidative species generated during photocatalysis were tracked by electron spin resonance (ESR) and Peroxidase method.All these results indicated that visible-light excited N-TiO2 can activate molecular oxygen and thereby achieve degradation of MC-LR completely within 14 h.The removal of 59% of TOC was achieved after 20 h irradiation.The major oxidative species in the system were hydroxyl radical (·OH) and H2O2.13 Kinds of intermediates were primarily identified in the process.Based on these results,a reasonable conclusion was drawn for the degradation of MC-LR wherein its four positions are easy to be attacked by the photo-generated OH radical followed by the hydrolyzation of peptides. | YANG Jing,CHEN DengXia,DENG AnPing,FANG YanFen,LUO GuangFu,LI DeJiang,LI RuiPing & HUANG YingPing Alan G.MacDiarmid Research Institute of Renewable Energy,China Three Gorges University,Yichang 443000,China | 2010 | Science China Chemistry2010，53，8： | 12 |
| 3 | 磷掺杂TiO2薄膜的制备与表征及其可见光照射下光催化降解邻苯二甲酸丁苄酯性能(英文)显示文摘P‐doped TiO2 (PTIO) thin‐films with different P contents were prepared using a sol‐gel method. The thin‐film samples were characterized using various techniques. The photocatalytic activity was evaluated by decomposing butyl benzyl phthalate under visible‐light irradiation. The results showed that the transformation of anatase to the rutile phase was inhibited and grain growth of TiO2 was prevented by P doping. The results confirm that the doped P atoms existed in two chemical forms, and those incorporated in the TiO2 lattice may play a positive role in photocatalysis. The high photocatalytic activities of the PTIO thin‐films may be the result of extrinsic absorption through the creation of oxygen vacancies, rather than excitation of the intrinsic absorption band of bulk TiO2 . The PTIO can be recycled with little depression of the photocatalytic activity. After six cycles, the photocatalytic activity of the PTIO film was still higher than 98%. | R.M.MOHAMED E.AAZAM | 2013 | 催化学报2013，34，6： | 10 |
| 4 | Facile synthesis of Zn(Ⅱ)-doped g-C3N4 and their enhanced photocatalytic activity under visible light irradiation显示文摘Zn(Ⅱ)-doped graphitic carbon nitride(g-C3N4)with high photodegradation activity was prepared by one facile step.The morphology and structure of the prepared Zn(Ⅱ)-doped g-C3N4 were investigated,and the results showed that Zn(Ⅱ)could self-disperse during the pyrolysis process and Zn–N bond was formed between g-C3N4 and Zn.The dope of Zn(Ⅱ)influenced the structure of g-C3N4.The performance of photocatalytic activity of Zn(Ⅱ)-doped g-C3 N4 series indicated that the doped g-C3N4 with a small quantity of Zn(0.10 wt%)exhibits the best photocatalytic performance.The photodegradation activity for methyl orange was 2 times higher than that of pure g-C3N4.However,the photocatalytic activity decreased with the further increased content of Zn,which may be attributed to the structure change of g-C3N4 and the interaction of Zn–N bond between Zn and g-C3N4.Moreover,Zn(Ⅱ)-doped g-C3N4 showed good recycling photocatalytic stability. | Zhao-Tian Wang Jun-Li Xu Hui Zhou Xia Zhang | 2019 | Rare Metals2019，38，5： | 10 |

At pH 11, upon visible light irradiation for 6 h in the presence of O2, Zn-TDTAPc-F was found to be highly effective for the degradation of phenol in aqueous solution, and the degradation rate of phenol was more than 95%. HPLC was used to confirm formic acid, fumaric acid and maleic acid as its main degradation products. | CHEN WenXing CHEN ShiLiang LüShenShui YAO YuYuan XU MinHong | 2007 | Science China Chemistry2007，50，3： | 8 |

| 7 | TiO2 sensitized by red-, green-, blue-emissive carbon dots for enhanced H2 production显示文摘Carbon dots(Cdots)with a broad light absorption range could be a potential stable sensitizer for TiO2,which is an excellent ultraviolet(UV)response photocatalyst.Herein,we systematically investigated the different color emissive Cdots-sensitized TiO2 for H2 production.Firstly,all kinds of Cdots enhanced the photocatalytic properties of TiO2.All the Cdots-sensitized TiO2 exhibits visible light H2 production due to their absorption in the visible light region.The photocurrent and H2 production amount display strong dependence on the light absorption range of Cdots.The blue-emissive Cdots endow the weak H2 production rate due to its weak absorption in the visible light.The enhanced photocatalytic activities are mainly contributed to the strong light absorbance and high-efficient charge separation.The light absorption of green-and red-emissive Cdots is another main factor for the high catalytic activities besides charge separation. | Dong-Xue Yang Dan Qu Xiang Miao Wen-Shuai Jiang Li An Yuan-Jing Wen Dan-Dan Wu Zai-Cheng Sun | 2019 | Rare Metals2019，38，5： | 8 |
| 8 | Common-anode LED on a Si substrate for beyond 15 Gbit/s underwater visible light communication显示文摘Visible light communication based on light-emitting diodes(LEDs) has become a promising candidate by providing high data rates, low latency, and secure communication for underwater environments. In this paper,a self-designed common-anode GaN-based five-primary-color LED(RGBYC LED) on a Si substrate is proposed and fabricated. The design of a common anode is used to mitigate the saturation effect for a low-frequency component. Additionally, compared with commercially available LEDs that suffer from nonlinearity distortion,applying the designed LED can provide much better and broader linearity according to the measurement results.Therefore, the modulation depth and system performance can be further improved to implement a high-speed underwater visible light communication(UVLC) system. There is no nonlinearity compensation algorithm applied due to the good linearity of the proposed LED;thus, the offline digital signal processing is simplified. We experimentally demonstrate 14.81 Gbit/s 64 quadrature amplitude modulation(QAM)-discrete multitone(DMT)and 15.17 Gbit/s bit-loading-DMT transmissions through a 1.2-m-long underwater channel based on the proposed RGBYC LED with an intrasymbol frequency-domain averaging channel estimation and zero-forcing equalization.As far as we know, this is the highest data rate for an LED-based UVLC system. | YINGJUN ZHOU XIN ZHU FANGCHEN HU JIANYANG SHI FUMIN WANG PENG ZOU JUNLIN LIU FENGYI JIANG NAN CHI | 2019 | Photonics Research2019，7，9： | 7 |
| 9 | Photocatalytic degradation of Rhodamine B under visible light with Nd-doped titanium dioxide films显示文摘Microporous titanium dioxide films were prepared by the sol-gel methods on glass substrates, using tetrabutyl titanate as source material. In order to absorb the visible light and increase the photocatalytic activities, different concentrations of neodymium ions (Nd/Ti molar ratio was 0.5%, 0.7%, 0.9%, and 1.1% respectively) were added into the sol. X-ray diffraction (XRD), X-ray photoelectron spectros-copy (XPS), and atom force microscopy (AFM) were applied to characterize the modified films. A kind of typical textile industry pollutant (Rhodamine B) was used to evaluate the photocatalytic activities of the films under visible light. The results showed that the activities of the films were improved by doping Nd ions into the sol. | WU Xiaohong SU Peibo LIU Huiling QI Lili | 2009 | Journal of Rare Earths2009，27，5： | 6 |
| 10 | Preparation and visible photocatalytic dye degradation of Mn-TiO2/sepiolite photocatalysts显示文摘The performance of Mn-TiO2/sepiolite photocatalysts prepared by the solgel method and calcinated at different temperatures was studied in the photocatalytic degradation of direct fast emerald green dye under visible light irradiation,and a series of analytical techniques such as XRD,SEM,FTIR,TG-DSC,XPS,UV-vis-DRS and Raman spectroscopy were used to characterize the morphology,structure and optical properties of the photocatalysts.It is found that the anatase TiO2 was formed in all photocatalysts.Mn4+might incorporate into the lattice structure of TiO2 and partially replace Ti4+,thus causing the defects in the crystal structure and the broadening of the spectral response range of TiO2.At the same time,TiO2 particles were dispersed on the surface of the sepiolite,which immobilized TiO2 particles with sepiolite via the bond of Ti-O-Si.Mn-TiO2/sepiolite calcined at 400°C exhibits the highest photocatalytic activity and the degradation rate of direct fast emerald green is up to 98.13%.Meanwhile,it also shows good stability and universality. | Pengfei Zhu Zhihao Ren Ruoxu Wang Ming Duan Lisi Xie Jing Xu Yujing Tian | 2020 | Frontiers of Materials Science2020，14，1： | 6 |
| 11 | Two-dimensional Sn2Ta2O7 nanosheets as efficient visible lightdriven photocatalysts for hydrogen evolution显示文摘Two-dimensional Sn2Ta2O7 nanosheets with a thickness of^10 nm were successfully prepared through a novel tantalic acid-based solid-state reaction method at reduced temperature.The as-obtained samples were characterized by powder X-ray diffraction(XRD),ultraviolet–visible(UV–Vis)diffuse reflectance spectra,scanning electron microscopy(SEM),transmission electron microscopy(TEM)and Brunauer–Emmett–Teller(BET)analysis.The photocatalytic performance of Sn2 Ta2 O7 nanosheets was evaluated by photocatalytic water splitting for hydrogen evolution under visible light irradiation(k C 400 nm).The Sn2Ta2O7 nanosheets with a large surface area of 25.9 m^2·g^-1 showed higher H2 production activity,which was about 4.4 times higher than that of bulk Sn2 Ta2O7 in lactic acid aqueous solutions using Pt as a cocatalyst.The improved photocatalytic performance mainly benefited from the nanosheet structure,which provided abundant surface active sites and facilitated the photogenerated charge carrier separation efficiently.This workmay open up new opportunity to develop novel nanostructured tantalum-based semiconductors with improved catalytic performance for solar energy conversion. | Xiao-Shuai Wang Chao Zhou Run Shi Qin-Qin Liu Tie-Rui Zhang | 2019 | Rare Metals2019，38，5： | 6 |
| 12 | Nano-Cu2O-loaded Paper: Green Preparation and High Visible Light Photocatalytic Performance for Formaldehyde Removal显示文摘The removal of formaldehyde (HCHO) from indoor air is of great importance to reduce health risks and improve indoor air quality. In this study, nano-Cu2O-loaded paper with superior photocatalytic activity under visible light for the removal of HCHO was fabricated through a green, simple, and fast in situ synthesis method. The optimum preparation conditions for nano-Cu2O-loaded paper were as follows: 2 g (oven-dry basis) cellulose fibers, CuSO4 dosage 8 g, NaOH dosage 1.6 g, temperature 80℃, 60 min for Cu2+ absorption, and 60 min for reaction. Under the optimum conditions, the Cu2O deposition ratio approached 30% and the nano-Cu2O-loaded paper exhibited a catalytic efficiency of approximately 97% for HCHO removal. The photocatalytic capacity of nano-Cu2O-loaded paper for HCHO removal had a positive correlation with the deposition ratio of nano Cu2O particles. Excellent antibacterial property of nano- Cu2O-loaded paper against Staphylococcus aureus and Escherichia coli was also confirmed. Moreover, nano-Cu2O-loaded paper was proven to be hydrophobic. | Lijian Sun Xin Xin Xianhui An Xueren Qian | 2019 | Paper And Biomaterials2019，4，3： | 6 |
| 13 | A novel n-CeO2/n-CdO heterojunction nanocomposite for enhanced photodegradation of organic pollutants under visible light irradiation显示文摘In this study,a series of novel visible light driven n-CeO2/n-CdO heterojunction(CeO2/CdO)nanoco mposites we re successfully fabricated by simple ultrasonication method.Several characte rization tools including X-ray diffraction(XRD),scanning electro n microscopy(SEM),transmission electron microscopy(TEM)and UV-vis diffuse reflectance spectroscopy(UV-DRS),etc.,were utilized to investigate the physicochemical properties of the catalyst and confirm the formation of heterojunction.Under visible light irradiations,the photocatalytic activities of the as-prepared CeO2/CdO nanocomposites were evaluated by degrading of Congo red(CR)and Rhodamine B(RhB)solutions.As a result,the CeO2/CdO(mass percentage ratio 1:3)nanocomposite displays remarkable performance for CR and RhB degradation.The enhancement in the photocatalytic performance of CeO2/CdO(1:3)nanocomposite can be attributed not only to the strong visible-light absorption region,separating the photogenerated electronhole pairs but also to the formation of n-n type heterojunction.The results also indicate that the CeO2/CdO(1:3)nanocomposite has good stabilization and high reusability.In addition,the mechanism is proposed for the coupled semiconductors and possible reasons for the enhancement of visible-light photocatalytic efficiency are also discussed.This work can provide a new gateway to fabricate visible photocatalysts and promising candidate catalysts for poisonous wastewater treatment in the near future. | Karunamoorthy Saravanakumar Subramani Muthupoongodi Velluchamy Muthuraj | 2019 | Journal of Rare Earths2019，37，8： | 6 |
| 14 | Fabrication of ultrafine ZnFe2O4 nanoparticles for efficient photocatalytic reduction CO2 under visible light illumination显示文摘A one-pot, solvent-thermal process was used to create the ultrafine ZnFe_2O_4 nanoparticles photocatalyst.During the solvent-thermal process, the in situ self-forming NaCl not only served as a 'cage' to confine the ion diffusion, but also acted as a microreactor for nanocrystallite growth. An average particle size of ~10 nm and a high-specific surface area of~112.9 m^2/g were observed for the ultrafine ZnFe_2O_4 nanoparticles Owing to the synergistic effect of ultrafine particle size, the full utilization of the visible light region and high conduction band(CB) position, ultrafine ZnFe_2O_4 photocatalyst displayed an efficient photocatalytic CO_2 reduction under visible light illumination. Besides, the ultrafine ZnFe_2 O_4 photocatalyst showed high production selectivity for CH_3CHO and C_2H_5OH generation in aqueous CO_2/NaHCO_3 solution. This work may provide a new idea for the synthesis of new high-efficiency photocatalysts. | Jun xiao Weiyi Yang Shuang Gao Caixia Sun Qi Li | 2018 | Journal of Materials Science & Technology2018，34，12： | 6 |
| 15 | VLC-Based Indoor Positioning Algorithm Combined with OFDM and Particle Filter显示文摘Visible light communications(VLC) have recently attracted a growing interest and can be a potential solution to realize indoor positioning,however,the performance of existing indoor positioning system is limited by multipath distortion inside a room.In order to combat the effect of multipath distortion,this paper proposes an LED-based indoor positioning algorithm combined with hybrid OFDM(HOFDM),in which asymmetrically clipped optical OFDM(ACOOFDM) is transmitted on the odd subcarriers while using pulse amplitude modulated discrete multitone(PAM-DMT) to modulate the imaginary part of each even subcarrier.In this scheme,we take a combined approach where a received-signal-strength(RSS) technique is employed to determine the location of the receiver and realize the 3-D positioning by Trust-region-based positioning.Moreover,a particle filter is used to further improve the positioning accuracy.Results confirm that this proposed positioning algorithm can achieve high accuracy even with multipath distortion,and the algorithm has better performance when combined with particle filter. | Jin Wang Haoxu Li Xiaofeng Zhang Rangzhong Wu | 2019 | China Communications2019，16，1： | 6 |
| 16 | Improvement of photocatalytic activity of high specific surface area graphitic carbon nitride by loading a co-catalyst显示文摘Graphitic carbon nitride(g-C3N4)was synthesized by heating melamine and was then treated with sodium hydroxide solution under a hydrothermal condition to obtain g-C3N4 with a large specific surface area(HSSA).HSSA shows higher photocatalytic activity for decomposition of acetaldehyde than that of original g-C3N4.HSSA was modified with RuO2 as a co-catalyst by the impregnation method.HSSA loaded with 0.05 wt%RuO2 shows the highest photocatalytic activity for acetaldehyde decomposition under visible light(k=455 nm). | Ye Chen Naoya Murakami Hai-Yan Chen Jia Sun Qi-Tao Zhang Zhi-Feng Wang Teruhisa Ohno Ming Zhang | 2019 | Rare Metals2019，38，5： | 5 |
| 17 | Modeling of Multipath Channel and Performance Analysis of MIMO-DCO-OFDM System in Visible Light Communications显示文摘When a big path difference exists between the multiple transmitter-receiver links, time dispersion is inevitable. A multipath channel model is proposed for Multiple-input multiple-output(MIMO)Visible light communications(VLC). To combat Intersymbol interference(ISI) as well as increase the channel capacity, a combination of MIMO and Direct-currentbiased Optical orthogonal frequency division multiplexing(DCO-OFDM) is studied. The performance analysis of MIMO-DCO-OFDM taking into account the limitation of the forward current of the off-the-shelf LED is derived.The accuracy of the theoretical results is verified by comparison with the Monte Carlo Bit error ratio(BER)simulation results under different DC bias and different clipping levels. | JIA Kejun HAO Li | 2019 | Chinese Journal of Electronics2019，28，3： | 5 |
| 18 | All-solid-state BiVO4/ZnIn2S4 Z-scheme composite with efficient charge separations for improved visible light photocatalytic organics degradation显示文摘Constructing a Z-scheme is a significant approach to improve the separation of photogene rated carriers for effective organic pollutant degradation.Herein,a BiVO4/ZnIn2S4(BZ) Z-scheme composite was successfully synthesized,and applied to photodegrade methyl orange(MO) irradiated by a LED lamp.Anchoring the BiVO4 on the ZnIn2S4 nanoparticles promoted the separation of photogenerated electronholes and broadened the light response range.The detailed characterizations,including surface morphology,elements valence state,and photocurrent performance,demonstrated that the enhanced separation of photogenerated carriers was the pivotal reason for the enhanced photocatalysis reaction.Benefiting from the excellent photocatalytic characteristics,the 5% mass ratio of BZ composite presented the highest MO degradation rate of 0.00997 min^-1,which was 1.9 and 10.3 times greater than the virgin ZnIn2S4 and BiVO4,respectively.Furthermore,the BZ hybrid materials indicated a well photo-stability in the four recycling tests. | Deling Yuan Mengting Sun Shoufeng Tang Yating Zhang Zetao Wang Jinbang Qi Yandi Rao Qingrui Zhang | 2020 | Chinese Chemical Letters2020，31，2： | 5 |
| 19 | Boosting photocatalytic degradation of RhB via interfacial electronic effects between Fe-based ionic liquid and g-C_3N_4显示文摘The Fe-based ionic liquid doped g-C_3N_4(Fee CN) photocatalyst was firstly prepared base on ultrathin g-C_3N_4 obtained by multiple calcination method with a metal-based reactive ionic liquid [Omim]FeCl_4 for the degradation of Rhodamine B(RhB). Experimental results revealed that Fe3+species were doped into the framework of g-C_3N_4. The effect of the amount of Fe-doping on the catalytic activity was performed. The result showed that the Fee CN could effectively degrade RhB under the condition of visible light irradiation. The photocurrent analysis showed that the incorporation of Fe^(3+)into g-C_3N_4 material could accelerate the separation of the photogenerated carriers significantly.At the same time, the reactive species generated during the photodegradation process were tested by radicals trapping experiments and electron spin resonance(ESR). It was proposed that the synergistic effect of■ and ·OH contributed to degrade RhB efficiently. | Xiaowei Li Bin Wang Yuhong Huang Jun Di Jiexiang Xia Wenshuai Zhu Huaming Li | 2019 | Green Energy & Environment2019，4，2： | 4 |
| 20 | 1.3 GHz E-O bandwidth GaN-based micro-LED for multi-gigabit visible light communication显示文摘The data rate of a visible light communication(VLC) system is basically determined by the electrical-to-optical(E-O) bandwidth of its light-emitting diode(LED) source. In order to break through the intrinsic limitation of the carrier recombination rate on E-O bandwidth in conventional c-plane LEDs based on In Ga N quantum wells,a blue micro-LED with an active region of nano-structured In Ga N wetting layer is designed, fabricated, and packaged to realize a high-speed VLC system. The E-O bandwidth of the micro-LED can reach up to 1.3 GHz. Based on this high-speed micro-LED, we demonstrated a data rate of 2 Gbps with a bit error rate(BER) of 1.2×10^(-3) with simple on-off keying signal for a 3-m real-time VLC. In addition, a 4-Gbps VLC system using quadrature phase shift keying-orthogonal frequency-division multiplexing with a BER of 3.2×10^(-3) is also achieved for the same scenario. Among all the point-to-point VLC systems based on a single-pixel LED,this work has the highest distance-bandwidth product of 3 GHz·m and the highest distance-rate product of 12 Gbps·m. | LEI WANG ZIXIAN WEI CHIEN-JU CHEN LAI WANG H.Y.FU LI ZHANG KAI-CHIA CHEN MENG-CHYI WU YUHAN DONG ZHIBIAO HAO YI LUO | 2021 | Photonics Research2021，9，5： | 4 |
