Mesoporous crystalline TiSnO (0 < x < 1) solid solution for a high-performance photocatalyst under visible light irradiation.

We report a facile and effective inorganic polycondensation combined with aerosol-spray strategy towards high-performance photocatalyst by fabricating mesoporous TiSnO (0 < x < 1) solid solution. Such TiSnO nanocrystals with high Sn-doped contents are self-assembled into mesoporous spheres can effectively promote visible-light harvest and high quantum yield, leading a longer lifetime of the photoelectron-hole pairs and less recombination. Such the photocatalysts enhanced photocatalytic activity for the degradation of Rhodamine B (RhB).
