英文摘要： Design and synthesis of semiconductor thin film with high light response area and low light scattering rate would play an important role in promoting the practical application of hydrogen production by photoelectrochemical water splitting. This project mainly aims at preparing continuous porous metal oxide {MxNyOz; M(or N)=Ti, Zr, Al, Fe, and so on} film on conductive substrate through czochralski method and spin-coating method, using polymer and metal mixture sol as precursor; in-depth studying the effect of constituents of precursor, calcining temperature, and sensitizing form on property of photocatalytic production hydrogen by solar energy; revealing the relationship between porous structure and photocatalytic activity; further investigating the mechanism of hydrogen production efficiency by photoelectrochemical water splitting; finally exploring new ways to improve the performance of hydrogen production. Meanwhile, implementation of this project would take an important academic significance on promoting cross-integration of such disciplines as chemistry, materials, environment and energy.
