| 1 | Preparation and photoactivity of thermosensitive polymer supported metallophthalocyanine显示文摘A novel reactive metallophthalocyanine derivative,zinc tetra(2,4-dichloro-1,3,5-triazine)aminophthalo-cyanine(Zn-TDTAPc),was prepared and immobilized on poly(N-isopropylacrylamide)(PNIPAAm) by covalent bonding to obtain a thermosensitive polymer(Zn-TDTAPc-g-PNIPAAm).Compared with zinc tetraaminophthalocyanine(Zn-TAPc),Zn-TDTAPc-g-PNIPAAm exhibits excellent solubility in water and in most organic solvents.Furthermore,it has a special thermosensitive property in water and the lower critical solution temperature(LCST) is 34.1℃.It was found that both dissolved and precipitated Zn-TDTAPc-g-PNIPAAm present high photoactivity evidenced by the experiment of photocatalytic degra-dation of 1,3-diphenylisobenzofuran(DPBF) in the presence of Zn-TDTAPc-g-PNIPAAm.These proper-ties suggest that it can be used potentially in photodynamic therapy(PDT). | CHEN WenXing LIU Fan LU WangYang SHEN XiaoYuan YAO YuYuan XU MinHong | 2008 | Science China Chemistry2008，51，6： | 5 |

| 3 | Paleoclimatic evolution indicated by major geochemical elements from aeolian sediments on the east of Qinghai Lake显示文摘As the largest inland lake of China, along with its unique landscape and geographical location, Qinghai Lake has got much atten- tion of the scientists for a long time. The precursors have done substantive researches by using the lake sediment, which deepen our understanding of the climate changes in this region. Although sand dunes and loess sediment are widely distributed around the lake, so far the researches on geochemical elements from aeolian sediment have been less reported. In this paper, we selected a typical aeolian profile on the east of Qinghai Lake. Based on systematic sampling and analysis of seven major geochemical elements, combined with OSL dating and previous researches, this paper discusses climate changes in the Qinghai Lake area since 12.5 ka B.P.. Our conclusions are: (1) Before 12.5 ka B.P., the climate in this region was dry, cold, and accompanied by strong wind-sand activities. (2) During 12.5-11.9 ka B.P., the climate became warm and wet. However, there was an abrupt climate cooling event during 12.2-11.9 ka B.P., which likely corresponded to the Younger Dryas event. (3) During 11.9-8.0 ka B.P., the climate fluctuated greatly and frequently from warm to cold, and three cooling events occurred. (4) During 8.0-2.6 ka B.P., the climate was warm and humid. (5) Since 2.6 ka B.P., similar to the modern climate, the climate was mainly dry and cold. | Yuan Shang RuiJie Lu FeiFei Jia LiHui Tian QingLiang Tang Yuan Chen Chao Zhao WangYang Wu | 2013 | Research in Cold and Arid Regions2013，5，3： | 2 |

| 6 | Synthesis and photoactivity of pH-responsive amphiphilic block polymer photosensitizer bonded zinc phthalocyanine显示文摘A zinc tetraaminophthalocyanine derivative, zinc tetra(methacryloyl moiety)aminophthalocyanine (MeZnAPc) (with a double bond) was synthesized by the reaction between zinc tetraaminophthalocyanine (ZnTAPc) and methacryloyl chloride. Atom transfer radical polymerization (ATRP) was employed as the polymerization technique to obtain a novel pH-responsive polymeric photosensitizer (PEG110-b-P(DPAn-co-MeZnAPcm)) by copolymerizing of methoxypolyethylene glycols (MPEG) (as reducing agent), 2-(isopropylamino)ethyl methacrylate (DPA) and MeZnAPc. This photosensitizer was characterized by UV-vis spectroscopy, FTIR, H NMR, etc. The results indicated that the photosensitizer presented the well pH-responsive be 1 havior around the pH range 6.0-6.5 and the high photoactivity to 1,3-diphenylisobenzofuran (DPBF). The result of photocatalysis oxidation of L-tryptophan (L-Try) suggested that zinc phthalocyanine could present high photoactivity due to its dispersivity at pH 5.5 without formation of micelles, and its photoactivity decreased dramatically at pH 7.4 due to wrapping ZnTAPc into the micelles. Therefore, the novel pH-responsive polymeric photosensitizer has better application prospects in the field of photodynamic therapy. | Lü WangYang SUN ChunMei LU Qin LI Nan WU DeZhou YAO YuYuan CHEN WenXing | 2012 | Science China Chemistry2012，55，6： | 1 |

| 9 | Analysis of photocatalytic degradation of polyamide microplastics in metal salt solution by high resolution mass spectrometry显示文摘Microplastic pollution has become one of the most concerned focuses in the world.Among many treatment methods,photocatalysis is considered to be one of the most environmentally friendly methods.In this work,the photodegradation behavior of polyamide microplastics is studied by using polyamide 6(PA6)as model microplastics and FeCl_(3) as catalyst.It is hoped that the PA6 fiber can be effectively degraded by utilizing the strong oxidizing active species that can be produced after FeCl_(3) is irradiated in water.The results shows that PA6 fiber can be almost completely degraded after 10 days of irradiation in FeCl_(3) aqueous solution,indicating that it is promising to use this new method to solve the problem of PA6type microplastics.In addition,the chain scission mechanism and degradation process of PA6 are analyzed in detail by ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS),which provides a new insight for the study of polymer degradation mechanism. | Yunjin Zhong Lebing Zhuo Wangyang Lu | 2024 | Journal of Environmental Sciences2024，，5： | 0 |
| 10 | Efficient elimination of carbamazepine using polyacrylonitrile-supported pyridine bridged iron phthalocyanine nanofibers by activating peroxymonosulfate in dark condition显示文摘The monoaminotrinitro iron phthalocyanine(FeMATNPc)is used to connect with isonicotinic acid(INA)for amide bonding and axial coordination to synthetic a unique catalyst FeMATNPc-INA,which is loaded in polyacrylonitrile(PAN)nanofibers by electrospinning.The introduction of INA destroys theπ-πconjugated stack structure in phthalocyanine molecules and exposes more active sites.The FeMATNPc-INA structure is characterized by X-ray photoelectron spectroscopy and UV-visible absorption spectrum,and the FeMATNPcINA/PAN structure is characterized by Fourier transform infrared spectroscopy and X-ray diffraction.The FeMATNPc-INA/PAN can effectively activate peroxymonosulfate(PMS)to eliminate carbamazepine(CBZ)within 40 minutes(PMS 1.5 mmol/L)in the dark.The effects of catalyst dosage,PMS concentration,pH and inorganic anion on the degradation of CBZ are investigated.It has been confirmed by electron paramagnetic resonance,gas chromatography–mass spectroscopy and free radical capture experiments that the catalytic system is degraded by·OH,SO4^(·-)and Fe(IV)=O are the major active species,the singlet oxygen(^(1)O_(2))is the secondary active species.The degradation process of CBZ is analyzed by ultra-high performance liquid chromatography-mass spectrometry and the aromatic compounds have been degraded to small molecular acids. | Zhexin Zhu Wenjie Qian Zhiguo Shang Xiaoji Ma Zhendong Wang Wangyang Lu Wenxing Chen | 2024 | Journal of Environmental Sciences2024，，3： | 0 |
| 11 | Degradation of carbamazepine by MWCNTs-promoted generation of high-valent iron-oxo species in a mild system with O-bridged iron perfluorophthalocyanine dimers显示文摘Metal phthalocyanine has been extensively studied as a catalyst for degradation of carbamazepine(CBZ).However,metal phthalocyanine tends to undergo their own dimerization or polymerization,thereby reducing their activity points and affecting their catalytic properties.In this study,a catalytic system consisting of O-bridged iron perfluorophthalocyanine dimers(FePcF16-O-FePcF16),multi-walled carbon nanotubes(MWCNTs)and H2O_(2) was proposed.The results showed MWCNTs loaded with FePcF16-O-FePcF16 can achieve excellent degradation of CBZ with smaller dosages of FePcF16-O-FePcF16 and H2O_(2),and milder reaction temperatures.In addition,the results of experiments revealed the reaction mechanism of non-hydroxyl radicals.The highly oxidized high-valent iron-oxo(Fe(IV)=O)species was the main reactive species in the FePcF16-O-FePcF16/MWCNTs/H2O_(2) system.It is noteworthy that MWCNTs can improve the dispersion of FePcF16-O-FePcF16,contributing to the production of highly oxidized Fe(IV)=O.Then,the pathway of CBZ oxidative degradation was speculated,and the study results also provide new ideas for metal phthalocyanine-loaded carbon materials to degrade emerging pollutants. | Zhiguo Zhao Moyan Zhou Nan Li Yuyuan Yao Wenxing Chen Wangyang Lu | 2021 | Journal of Environmental Sciences2021，33，1： | 0 |
| 12 | Facile fabrication of superior antibacterial cotton fabric based on ZnO nanoparticles/quaternary ammonium salts hybrid composites and mechanism study显示文摘In the research for the safe and efficiently antibacterial cotton fabrics to minimize risk for human health,an organic–inorganic hybrid material of ZnO nanoparticles(NPs)and quaternary ammonium salt(QAS)was employed to modify cotton fabrics by a dipping–padding–drying method.The synergistic effects of ZnO NPs and QAS on the structure and antibacterial properties of cotton fabrics were studied in detail.Results displayed that the QAS and ZnO NPs were immobilized firmly in cotton fabric by the formation of chemical covalent bonds and silica gel structure.ZnO/QAS/cotton had a good inhibitory effect on the growth of E.coli and S.aureus,with superior antibacterial efficiency of>99.99%.ZnO/QAS/cotton preserved good mechanical property,water absorbability,and limpness.We also provided a detailed analysis of antibacterial mechanism for the hybrid materials.The contact mechanism and the Zn2+release were considered as the main mechanisms for the ZnO/QAS/cotton,while the reactive oxygen species(ROS)generation only had a little contribution to the antibacterial activity.In short,the excellent integrated properties endowed the hybrid cotton fabrics as potential application in many fields,like healthcare,food packaging. | Yechen Hu Lin Zhang Yafeng Huang Xiufang Chen Fengtao Chen Wangyang Lu | 2023 | Frontiers of Materials Science2023，17，2： | 0 |
| 13 | Robust Co_(3)O_(4)nanocatalysts supported on biomass-derived porous N-doped carbon toward low-pressure hydrogenation of furfural显示文摘The catalytic conversion of biomass platform chemicals using abundant non-noble metal nanocatalysts is a challenging topic.Here,high-density cobalt oxide nanoparticles loaded on biomass-derived porous N-doped carbon(NC)was fabricated by a tandem hydrothermal pyrolysis and mild nitrate decomposition process,which is a green and cheap preparation method.The Co_(3)O_(4) nanoparticles with the average size of 12 nm were uniformly distributed on the porous NC.The nanocomposites also possessed large surface area,high N content,good dispersibility in isopropanol,and furfural absorbability.Due to these characteristics,the novel cobalt nanocatalyst exhibited high catalytic activity for producing furfuryl alcohol,yielding 98.7%of the conversion and 97.1%of the selectivity at 160℃ for 6 h under 1 bar H2.The control experiments implied that both direct hydrogenation and transfer hydrogenation pathways co-existed in the hydrogenation reaction.The excellent catalytic activity of Co_(3)O_(4)@NC was attributed to the cooperative effects of porous NC and Co_(3)O_(4) nanoparticles.This approach provides a new idea to design effective high-density nonnoble metal oxide nanocatalysts for hydrogenation reactions,which can make full use of sustainable natural biomass. | Lin Zhang Lanlan Cheng Yechen Hu Qingguang Xiao Xiufang Chen Wangyang Lu | 2023 | Frontiers of Materials Science2023，17，2： | 0 |
| 14 | Atom Recombination of Difluorocarbene Enables 3-Fluorinated Oxindoles from 2-Aminoarylketones显示文摘Contrary to the traditional implementation as a difluoromethyl group and recently disclosed role of C1 synthons in synthetic organic chemistry,difluorocarbene(:CF_(2))is reported herein to proceed in unprecedented atom recombination as both a C1 synthon and F1 reagent simultaneously to render valuable 3-fluorinated oxindoles from 2-aminoarylketones.The reaction does not require catalyst and features a broad range of substrates with good functional group compatibility and ease of execution.This transformation could be employed to the quick-constructions of certain bioactive molecule derivatives.The mechanistic experiments and density functional theory(DFT)calculations indicate that this atom recombination reaction of:CF_(2) for the synthesis of 3-fluorinated oxindoles may involve a rearrangement process of epoxide intermediates. | Guan Zhang Qianqian Shi Mengyuan Hou Kai Yang Shihui Wang Shuai Wang Wangyang Li Chaokun Li Jian Qiu Hetao Xu Lu Zhou Cece Wang Shi-Jun Li Yu Lan Qiuling Song | 2022 | CCS Chemistry2022，4，5： | 0 |
| 15 | In-situ-reduced synthesis of cyano group modified g-C_(3)N_(4)/CaCO_(3) composite with highly enhanced photocatalytic activity for nicotine elimination显示文摘Graphite carbon nitride has many excellent properties as a two-dimensional semiconductor material so that it has a wide application prospect in the field of photocatalysis.However,the traditional problems such as high recombination rate of photogenerated carriers limit its application.In this work,we introduce nitrogen deficiency into g-C_(3)N_(4)to solve this problem a simple and safe in-situ reduction method.g-C_(3)N_(4)/CaCO_(3)was obtained by a simple and safe one-step calcination method with industrial-grade micron particles CaCO_(3).Cyano group modification was in-situ reduced during the thermal polymerization process,which would change the internal electronic structure of g-C_(3)N_(4).The successful combination of g-C_(3)N_(4)and CaCO_(3)and the introduction of cyanide have been proved by Fourier transform infrared spectroscopy and X-ray photoelectron spectrometer.The formation of the cyano group,an electron-absorbing group,promotes the effective separation of photogenic electron hole pairs and inhibits the recombination of photogenic carriers.These advantages result in the generation of more·O_(2)-and1O_(2)in the catalytic system,which increases the photocatalytic efficiency of nicotine degradation by ten times.Furthermore,the degradation process of nicotine has been studied in this work to provide a basis for the degradation of nicotine organic pollutants in the air. | Chenxiao Qi Haixiang Chen Xiufang Chen Chengyu Chu Xueting Mei Wangyang Lu Nan Li | 2023 | Journal of Environmental Sciences2023，，4： | 0 |
