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 photo-electrodes and understanding of the working mechanism are required from the perspective of improving light absorption, charge kinetics and surface catalysis.
