Abstract

Recently, great progress has been achieved in well-controlled syntheses of definite shaped nanocrystals (NCs) exposed with different facets, which provides us opportunities to make systematic and deep studies on the surface structures of the functional NCs and their performances in real applications. In this paper, we reported our systematic works how to selectively expose the highly active facets (especially the {001} high-energy facets) of TiO₂ NCs, by which the catalytic activities of TiO₂ NCs in the photochemical processes including photocatalytic degradation of organic pollutants and photocatalytic water splitting have been markedly enhanced.
