Herein , we demonstrate that the photocatalytic activity of anatase TiO ( 2 ) nanocrystals in both photoreduction and photooxidation processes can be enhanced by selectively depositing Pt nanoparticles on the { 101 } facets , which strengthens spontaneously surface - induced separation between photogenerated electrons and holes in the photocatalysis process .
