Abstract:
TiO2 films consisting of single-crystal anatase nanoparticles with exposed {001} facets were fabricated from anodized TiO2 nanotube arrays. The films' photocatalytic activities were further activated and then enhanced (∼2.5 times) by removing F(-) from the {001} facets. This study indicates that fluorine-free crystal surfaces are of great importance for the application of such kinds of single-crystal TiO2 nanoparticle films with exposed {001} facets in related areas.
