چکیده انگلیسی
Hierarchical porous anatase TiO2 nanosheets exposed with the high-reactive {001} facets were synthesized by a simple hydrothermal method. Each TiO2 nanosheet is found to be composed of several much thinner {001} facets dominated nanosheets, hence the specific surface area and the percentage of the {001} facets were significantly enlarged. The thinner nanosheet also facilitates the transport of the photogenerated electrons and holes to the particle surface, resulting in the formation of a large amount of high-reactive radicals and holes for photocatalystic oxidation reaction. Remarkably, due to the special structure of as-prepared TiO2, it exhibits a superior photocatalytic degradation capacity for organic dyes than microsized anatase TiO2 sheet dominated by the {001} facets.
