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.
