Abstract

TiO₂ films composed of flower-like TiO₂ microspheres with exposed {001} facets were synthesized by a simple one-pot hydrothermal method and exhibited tunable photocatalytic selectivity towards decomposition of azo dyes in water by modifying the surface of TiO₂ microspheres as well as by varying the degree of etching of {001} facets.
