| 1 | Atomic-level insights into surface engineering of semiconductors for photocatalytic CO_(2) reduction显示文摘Photocatalytic conversion of CO_(2)into solar fuels provides a bright route for the green and sustainable development of human society.However,the realization of efficient photocatalytic CO_(2)reduction reaction(CO_(2)RR)is still challenging owing to the sluggish kinetics or unfavorable thermodynamics for basic chemical processes of CO_(2)RR,such as adsorption,activation,conversion and product desorption.To overcome these shortcomings,recent works have demonstrated that surface engineering of semiconductors,such as introducing surface vacancy,surface doping,and cocatalyst loading,serves as effective or promising strategies for improved photocatalytic CO_(2)RR with high activity and selectivity.The essential reason lies in the activation and reaction pathways can be optimized and regulated through the reconstruction of surface atomic and electronic structures.Herein,in this review,we focus on recent research advances about rational design of semiconductor surface for photocatalytic CO_(2)RR.The surface engineering strategies for improved CO_(2)adsorption,activation,and product selectivity will be reviewed.In addition,theoretical calculations along with in situ characterization techniques will be in the spotlight to clarify the kinetics and thermodynamics of the reaction process.The aim of this review is to provide deep understanding and rational guidance on the design of semiconductors for photocatalytic CO_(2)RR. | Hengming Huang Hui Song Jiahui Kou Chunhua Lu Jinhua Ye | 2022 | Journal of Energy Chemistry2022，31，4： | 1 |
| 2 | Bridging localized electron states of pyrite-type C0S_(2) cocatalyst for activated solar H_(2) evolution显示文摘The development of low-cost and high-active cocatalysts is one of the most significant links for photocatalytic water splitting.Herein,a novel strategy of electron delocalization modulation for transition metal sulfides has been developed by anion hybridization.P-modified CoS_(2)(CoS_(2)|P)nanocrystals were firstly fabricated via a gas-solid reaction and coupled with CdS nanorods to construct a composite catalyst for solar H2 evolution reaction(HER).The CdS/CoS_(2)|P catalyst shows an HER rate of 57.8 pmol h-1,which is 18 times that of the bare CdS,8 times that of the CdS/CoS2,and twice that of Pt/CdS.The reduced energy barrier and suppressed reverse reaction for HER on the catalyst have been predicted and explained by density functional theory(DFT)calculation.The underlying design strategy of novel cocatalysts by electron delocalization modulation may shed light on the rational development of other advanced catalysts for energy conversion. | Hengming Huang Chen Xue Zhenggang Fang Zhiliang Wang Bin Luo Menglong Sun Ling Zhou Kan Hu Jiahui Kou Lianzhou Wang Chunhua Lu | 2022 | Nano Research2022，15，1： | 0 |
| 3 | Metal-free π-conjugated hybrid g-C_(3)N_(4) with tunable band structure for enhanced visible-light photocatalytic H_(2) production显示文摘Development of low-cost and efficient photocatalytic materials with visible-light response is of urgent need for solving energy and environmental problems.Here,a metal-free two-dimensional(2D)π-conjugated hybrid g-C_(3)N_(4)photocatalyst with tunable band structure was prepared by a novel one-pot bottom-up method based on a supersaturated precipitation process of urea and triethanolamine(TEOA)solution.The microstructure of the hybrid g-C_(3)N_(4)is revealed to be a compound of periodic tri-s-triazine units grafted with N-doped graphene(GR)fragments.From experimental evidence and theoretical calculations,the two differentπ-conjugated fragments in the hybrid g-C_(3)N_(4)material are proved to construct a 2D in-plane junction structure,thereby expanding the light absorption range and accelerating the interface charge transfer.Theπ-conjugated electron coupling in the 2D photocatalyst eliminates the grain boundary effect,and the coupled highest occupied molecular orbital(HOMO)effectively promotes the separation of photo-induced charge carriers.Compared with the g-C_(3)N_(4)prepared by the conventional method,the visible-light H2 production activity of the optimized sample is enhanced by 253%.This work provides a new strategy of constructing metal-free g-C_(3)N_(4)hybrids for efficient photocatalytic water splitting. | Hengming Huang Kan Hu Chen Xue Zhiliang Wang Zhenggang Fang Ling Zhou Menglong Sun Zhongzi Xu Jiahui Kou Lianzhou Wang Chunhua Lu | 2021 | Journal of Materials Science & Technology2021，，28： | 0 |
