Most of previous researches on photocatalytic water splitting for H2 are focused on the photocatalysts synthesis, especially in material chemistry. So high quantum yields of hydrogen from photocatalytic water splitting have been reported. However, H2 and O2 must be separated in the scale-up process to avoid the potential explosion. From the viewpoint of chemical reaction engineering, a safe solar hydrogen production is important in commercial scale-up. The objective of this proposal is to develop chemical reactors that can separate hydrogen and oxygen in photocatalytic water splitting. This 3-year proposal is expected to (1) screen the best catalysts for photocatalytic water splitting, including Au/TiO2, InTaO4 and dual catalysts Bi(NO3)3 /Na3VO4, and search the optimum photo reaction conditions in the first year; (2) design a photochemical reactor that can directly separate hydrogen and oxygen in photocatalytic water splitting. Perform the photocatalytic water splitting using real solar energy in the second year; (3) design a z-scheme membrane reactor that can directly separate hydrogen and oxygen in photocatalytic water splitting. The result is expected to be a competitive solar-hydrogen production compared with other methods. Such technique would be a great contribution in sustainable energy.光催化水分解太陽光能氫氣再生能源photocatalytic water splittingsolar energyhydrogenrenewable energy
