摘要: Efficient overall photocatalytic water splitting for hydrogen production is still a huge challenging task for the photocatalysis society. Semiconductor based assembly of photocatalytic water splitting system carried out in our laboratory will be presented. We are trying to develop low cost visible light absorbing materials, efficient water oxidation and water reduction co-catalysts, and coupling them into an integrated functional photocatalytic cyclic system for efficient overall water splitting by proper junctions. In this approach, it was found that proper choice of redox matching water oxidation and proton reduction cocatalysts and tailor designing the lattice matching junctions between the base semiconductor and cocatalysts plays crucial role. Remarkable synergistic effect on the photocatalytic activity for overall water splitting was found when water oxidation and reduction cocatalysts were coloaded on base semiconductors. Throughout the talk, the key challenging scientific issues in water splitting will be discussed. In the meantime, solar energy related research programs in China will also be briefly introduced, emphasizing that China is now providing great opportunities for the home and abroad scientists to work in China or foster international cooperation/collaboration to challenge this holy grail of science—power the world by the solar energy conversion.
