Mesoporous hollow black TiO with controlled lattice disorder degrees for highly efficient visible-light-driven photocatalysis.

Black TiO has received tremendous attention because of its lattice disorder-induced reduction in the TiO bandgap, which yields excellent light absorption and photocatalytic ability. In this report, a highly efficient visible-light-driven black TiO photocatalyst was synthesized with a mesoporous hollow shell structure. It provided a higher specific surface area, more reaction sites and enhanced visible light absorption capability, which significantly promoted the photocatalytic reaction.
