Cubic anatase TiO2 nanocrystals with enhanced photocatalytic CO2 reduction activity

Single-crystalline anatase TiO2 nanocubes with exposed {100} and {001} facets, prepared by hydrothermal and calcination methods, display especially high photocatalytic activity toward CO2 reduction to methane and methanol, due to the synergistic effects of better crystallization, a more negative conduction band position and co-exposed {100} and {001} facets.
