Abstract

TiO₂ hierarchical microsphere assembled from anatase TiO₂ nanosheets has been successfully prepared and exhibited excellent catalytic activities of H₂ production and benzyl alcohol selective oxidized to benzaldehyde. These enhanced photoactivity can be mainly ascribed to the charge separation promoted by the surface F and nanosheet units, enhancement of substrate molecular transport profited from the hierarchical structure.
