The Invited Perspective on “Photoelectrocatalytic Water Splitting” Was Published on ACS Catalysis
In these years, our research on photoelectrocatalytic (PEC) water splitting has drawn worldwide attention. And the invited perspective “Photoelectrocatalytic Water Splitting: Significance of Cocatalysts, Electrolyte, and Interfaces” was recently published on ACS Catalysis. ( Chunmei Ding, Can Li*, et al., ACS Catal., 2017, 7, 675-688).
PEC water splitting is one of the ideal strategies of solar fuel production. And the solar-to-hydrogen (STH) efficiency is affected by many factors, and it is the production of the light absorption, charge separation, and charge injection efficiencies. To date, the efficiency of PEC water splitting is still far from the criterion for practical utilization, because many critical scientific issues are still unsolved, including the limited light absorption, sever charge recombination, high overpotential and slow kinetics of surface reactions, and poor stability of electrodes, etc. Since the group of Prof. Can Li initiated the research of PEC water splitting several years ago, great progress has been obtained on the fabrication of photoelectrodes (Nanoscale, 2014, 6, 2061; Phys. Chem. Chem. Phys., 2014, 16, 23544; Adv. Energy Mater. 2016, 1600864.), modification of cocatalysts (Phys. Chem. Chem. Phys., 2013, 15, 4589; ACS Appl. Mater. Interfaces 2015, 7, 3791; ChemSusChem 2015, 8, 3987.), effects of the electrolyte (J. Phys. Chem. B, 2015, 119, 3560.), charge storage and transport layers (Angew. Chem. Int. Ed. 2014, 53, 7295; Chem. Eur. J. 2015, 21, 9624; J. Phys. Chem. C 2015, 119, 19607; Energy Environ. Sci., 2016,9, 1327.), the electron-transport layer (ACS Appl. Mater. Interfaces, 2015, 7, 3791), manipulation of the interfacial energetics (J. Am. Chem. Soc., 2016, 138 (41), 13664.), construction of heterojunction (Chem. Sci. , 2016, 7, 6076.) and particle-particle interface charge transfer (Chem. Sci. , 2016, 7, 4391.), etc.
