Bio-template approach was employed to construct inverse V-type TiO2-based photocatalyst with well distributed AgBr in TiO2 matrix by making dead Troides Helena wings with inverse V-type scales as the template. A cross-linked titanium precursor with homogenous hydrolytic rate, good liquidity, and low viscosity was employed to facilitate a perfect duplication of the template and the dispersion of AgBr based on appropriate pretreatment of the template by alkali and acid. The as-synthesized inverse V-type TiO2/AgBr can be turned into inverse V-type TiO2/Ag-0 from AgBr photolysis during photocatalysis to achieve in situ deposition of Ag-0 in TiO2 matrix, by this approach, to avoid the deformation of surface microstructure inherited from the template. The result showed that the cooperation of perfect inverse V-type structure and the well distributed Ti02/Ag microstructures can efficiently boost the photosynthetic water oxidation compared to non-inverse V-type TiO2/Ag-0 and TiO2/Ag-0 without using template. The antireflection function of inverse V-type structure and the plasmatic effect of Ag-0 might be able to account for the enhanced photon capture and efficient photoelectric conversion.
