| 1 | Enhanced RuBisCO activity and promoted dicotyledons growth with degradable carbon dots显示文摘The ~ 5 nm degradable carbon dots (CDs) were synthesized directly from carbon rod by a one-step electrochemical method at room temperature.The as-prepared CDs can effectively enhance the ribulose bisphosphate carboxylase oxygenase (RuBisCO) activity,and then promote the dicotyledons growth (soybean,tomato,eggplant and so on) and finally increase their yields.Here,we used Arabidopsis thaliana and Trifolium repens L.as model plants to systematically study the beneficial effects of CDs on plant growth.These include:(i) accelerating seed germination;(ii) enlarging root elongation;(iii) increasing metal ions absorption and delivery;(iv) improving enzymes activity;(v) enhancing the carbohydrate content;(vi) degradation into plant hormone analogues and CO2;and finally (vii) enhancing the grain production by about 20%. | Hao Li Jian Huang Yang Liu Fang Lu Jun Zhong Yong Wang Shuiming Li Yeshayahu Lifshitz Shuit-Tong Lee Zhenhui Kang | 2019 | Nano Research2019，12，7： | 8 |
| 2 | One-step synthesis of cobalt,nitrogen-codoped carbon as nonprecious bifunctional electrocatalyst for oxygen reduction and evolution reactions显示文摘It is highly desired for the development of efficient bifunctional electrocatalyst for both oxygen reduction reaction(ORR) and oxygen evolution reaction(OER) in renewable energy technologies. In this work,cobalt, nitrogen-codoped carbon was prepared by a facile one-step method and demonstrated to exhibit good electrocatalytic performance for ORR and OER via a complete four-electron process. Besides, the catalyst prepared at900 °C also displayed excellent stability for both ORR and OER. Furthermore, the origin of catalytic activity was also explored, which was attributed to the synergistic effects of metallic Co and quaternary N. | Sijie Guo Yanmei Yang Naiyun Liu Shi Qiao Hui Huang Yang Liu Zhenhui Kang | 2016 | Science Bulletin2016，61，1： | 7 |
| 3 | A carbon dot-based total green and self-recoverable solid-state electrochemical cell fully utilizing H_(2)O_(2)redox couple显示文摘Electrochemical cell can overcome the inherent intermittence of the renewable energy sources,thus showing great potentials in applications ranging from elec-trical energy storage to future smart grid.However,the current electrochemical cells could not achieve the“total green”feature by fully utilizing the clean and abundant O_(2)/H_(2)O redox couples due to the enormous overpotentials for both oxygen reduction reaction(ORR)and oxygen release reaction(OER).Herein,we report a“total green”electrochemical composite film cell based on carbon dots(CDots),which can realize both ORR and OER in the acid environment.The in-air voltage generation(0.95 V,with a maximum power of 5.3μW)relies on the multiple-electron-transfer redox chemical reaction between the two active components inside the composite film,that is,ORR/OER of CDots and the redox reaction of polyaniline(PANI)on the electrode and the resulting proton concentration gradient.Interestingly,the cell can be self-recovered at low load,recharged by adding H_(2)O_(2),or electrocharged at high load.We anticipate that current study may open up new opportunities for designing and developing total-green energy storage and conversion systems for diverse applications. | Zhaomin Chen Xiaoqing Gu Yutong Guo Xin Wang Mingwang Shao Bin Dong Zhenhui Kang | 2021 | SusMat2021，1，3： | 2 |
| 4 | In-situ transient photovoltage study on interface electron transfer regulation of carbon dots/NiCo_(2)O_(4) photocatalyst for the enhanced overall water splitting activity显示文摘Photocatalytic hydrogen production by overall water solar-splitting is a prospective strategy to solve energy crisis.However,the rapid recombination of photogenerated electron–hole pairs deeply restricts photocatalytic activity of catalysts.Here,the in-situ transient photovoltage(TPV)technique was developed to investigate the interfacial photogenerated carrier extraction,photogenerated carrier recombination and the interfacial electron delivery kinetics of the photocatalyst.The carbon dots/NiCo_(2)O_(4)(CDs/NiCo_(2)O_(4))composite shows weakened recombination rate of photogenerated carriers due to charge storage of CDs,which enhances the photocatalytic water decomposition activity without any scavenger.CDs can accelerate the interface electron extraction about 0.09 ms,while the maximum electron storage time by CDs is up to 0.7 ms.The optimal CDs/NiCo_(2)O_(4)composite(5 wt.%CDs)displays the hydrogen production of 62µmol·h^(−1)·g^(−1) and oxygen production of 29µmol·h^(−1)·g^(−1) at normal atmosphere,which is about 4 times greater than that of pristine NiCo_(2)O_(4).This work provides sufficient evidence on the charge storage of CDs and the interfacial charge kinetics of photocatalysts on the basis of in-situ TPV tests. | Haodong Nie Yan Liu Yi Li Kaiqiang Wei Zhenyu Wu Hong Shi Hui Huang Yang Liu Mingwang Shao Zhenhui Kang | 2022 | Nano Research2022，15，3： | 2 |
| 5 | Optoelectronic and photocatalytic properties of I–III–VI QDs: Bridging between traditional and emerging new QDs显示文摘Due to the quantum size effect and other unique photoelectric properties,quantum dots(QDs)have attracted tremendous interest in nanoscience,leading a lot of milestone works.Meantime,the scope and scientific connotation of QDs are constantly expanding,which demonstrated amazing development vitality.Besides the well-developed Cd-containing Ⅱ-Ⅵ semiconductors,QDs of environmentally friendly Ⅰ-Ⅲ-Ⅵ(Ⅰ=Cu,Ag;Ⅲ=Ga,In;Ⅵ=S,Se)chalcogenides have been a hot spot in the QDs family,which are different from traditional Ⅱ-Ⅵ QDs in terms of multi-composition,complex defect structure,synthetic chemistry and optical properties,bringing a series of new laws,new phenomena and new challenges.The composition of Ⅰ-Ⅲ-Ⅵ chalcogenides and their solid solutions can be adjusted within a very large range while the anion framework remains stable,giving them excellent capability of photoelectric property manipulation.The important features of Ⅰ-Ⅲ-Ⅵ QDs include wide-range bandgap tuning,large Stokes shift and long photoluminescence(PL)lifetime,which are crucial for biological,optoelectronic and energy applications.This is due to the coexistence of two or more metal cations leading to a large number of intrinsic defects within the crystal lattice also known as deep-donor-acceptor states,besides the commonly observed surface defects in all QDs.However,a profound understanding of their structure and optoelectronic properties remains a huge challenge with many key issues unclear.On one hand,the achievements and experience of traditional QD research are expected to provide vital value for further development of Ⅰ-Ⅲ-Ⅵ QDs.On the other hand,the understanding of the emerging new QDs,such as carbon and other 2D materials,are even more challenging because of the dramatically different composition and structure from Ⅱ-Ⅵ semiconductors.For this,Ⅰ-Ⅲ-Ⅵ QDs,as a close relative to Ⅱ-Ⅵ QDs but with much more complex composition and structure variation,provide a great opportunity as a gradual bridge to make up the big gap between traditional QDs and emerging new QDs,such as carbon dots.Here,we hope to compare the research progress of Ⅰ-Ⅲ-Ⅵ QDs and Ⅱ-Ⅵ QDs,in an effort to comprehensively understand their structure,synthetic chemistry,optical electronic and photocatalytic properties.We further give insights on the key potential issues of Ⅰ-Ⅲ-Ⅵ QDs from the perspective of bridging between traditional QDs and emerging carbon dots,especially the profound principles behind synthetic chemistry,PL mechanism and optoelectronic applications. | Yanhong Liu Fenghua Li Hui Huang Baodong Mao Yang Liu Zhenhui Kang | 2020 | Journal of Semiconductors2020，41，9： | 2 |

| 15 | A core-satellite structured type Ⅱ heterojunction photocatalyst with enhanced CO_(2) reduction under visible light显示文摘Photocatalytic reduction of carbon dioxide into valuable chemicals is a sustainable and promising technology that alleviates the greenhouse effect and energy crisis.In this study,the Mn_(3)O_(4)/FeNbO_(4) type Ⅱ heterojunction photocatalyst with a core-satellite structure was synthesized by the facile soft chemical method.The formation of a nano-heterojunction is supposed to effectively improve light capture,charge transfer,and interfacial charge separation in the photochemical reaction.Meanwhile,the heterojunction has a good ability to capture and activate CO_(2).Our results show that the prepared Mn_(3)O_(4)/FeNbO_(4) photocatalyst exhibit obvious enhanced catalytic properties in the photocatalytic CO_(2) reduction reaction,where the CH_(4) yielding rate is 1.96 and 9.81 times those of FeNbO_(4) and Mn_(3)O_(4),respectively.The transient photovoltage test(TPV)shows that the low frequency electrons are crucial to the effective transfer of photogenerated electrons and holes in the Mn_(3)O_(4)/FeNbO_(4) nano heterojunctions.Analysis of in situ Fourier transform infrared spectroscopy(FTIR)verifies the effective CO_(2) adsorption on the Mn_(3)O_(4)/FeNbO_(4) surface and the high selectivity of CH_(4) products.These properties of the Mn_(3)O_(4)/FeNbO_(4) photocatalyst infer its broad prospects in the fields of carbon fixation and energy conservation. | Yuanyuan Cheng Yixian Liu Yunliang Liu Yaxi Li Ruqiang Wu Yongchao Du Najmeh Askari Naiyun Liu Fen Qiao Chenghua Sun Zhenhui Kang Haitao Li | 2022 | Nano Research2022，15，10： | 1 |
| 16 | Highly efficient metal-free catalyst from cellulose for hydrogen peroxide photoproduction instructed by machine learning and transient photovoltage technology显示文摘Great attention has been paid to green procedures and technologies for the design of environmental catalytic systems.Biomassderived catalysts represent one of the greener alternatives for green catalysis.Photocatalytic production of hydrogen peroxide(H_(2)O_(2))from O_(2) and H_(2)O is an ideal green way and has attracted widespread attention.Here,we show a metal-free photocatalyst from cellulose,which has a high photocatalytic activity for the photoproduction of H_(2)O_(2) with the reaction rate up to 2,093μmol/(h·g)and the apparent quantum efficiency of 2.33%.Importantly,a machine learning model was constructed to guide the synthesis of this metal-free photocatalyst.With the help of transient photovoltage(TPV)tests,we optimized their fabrication and catalytic activity,and clearly showed that the formation of carbon dots(CDs)facilitates the generation,separation,and transfer of photo-induced charges on the catalyst surface.This work provides a green way for the highly efficient metal-free photocatalyst design and study from biomass materials with the machine learning and TPV technology. | Yan Liu Xiao Wang Yajie Zhao Qingyao Wu Haodong Nie Honglin Si Hui Huang Yang Liu Mingwang Shao Zhenhui Kang | 2022 | Nano Research2022，15，5： | 1 |

| 20 | A photoactive process cascaded electrocatalysis for enhanced methanol oxidation over Pt-MXene-TiO2 composite显示文摘Highly efficient photo-assisted electrocatalysis for methanol oxidation reaction(MOR)realizes the conversion of solar and chemical energy into electric energy simultaneously.Here we report a Pt-MXene-TiO2 composite for highly efficient MOR via a photoactive cascaded electro-catalytic process.With light(UV and visible light)irradiation,MXene-TiO2 serves as the photo active centre(photoinduced hole)to activate the methanol molecules,while Pt particles are the active centre for the following electro-catalytic oxidation of those activated methanol molecules.Pt-MXene-TiO2 catalyst exhibits a lower onset potential(0.33 V)and an impressive mass activity of 2,750.42 mA·mg^−1 Pt under light illumination.It represents the highest MOR activity ever reported for photo-assisted electrocatalysts.Pt-MXene-TiO2 also shows excellent CO tolerance ability and stability,in which,after long-term(5,000 s)reaction,still keeps a high mass activity of 1,269.81 mA·mg−1Pt(62.66%of its initial activity).The photo-electro-catalytic system proposed in this work offers novel opportunities for exploiting photo-assisted enhancement of highly efficient and stable catalysts for MOR. | Yue Sun Yunjie Zhou Yan Liu Qingyao Wu Mengmeng Zhu Hui Huang Yang Liu Mingwang Shao Zhenhui Kang | 2020 | Nano Research2020，13，10： | 1 |
