摘要

Solar-driven catalysis represents a promising strategy and an important approach to provide clean energy and renewable fuels.After decades of research on solar-driven catalysis,scientists are now focusing on module design,mechanistic study,and practical application along with catalyst design [1-6].In the solar-driven catalysis process,light absorption,charge transport and surface redox reaction are the three critical factors,which all determine the solar to chemical energy conversion efficiency [7,8].Solar-to-hydrogen conversion is one of the major panels of solar-driven catalysis,in which hydrogen can be produced through the reduction of water by photogenerated electrons [9].To achieve high productivity of molecular hydrogen,rational design of photoelectrodes and understanding of the working mechanism are required from the perspective of improving light absorption,charge kinetics and surface catalysis.
