Abstract:

This study aimed at getting insight into the promoting effect of nonmetal ion(N and C) doping and hierarchically 3D dendrimeric architecture on mesoporous TiO2 based photocatalysts for efficient visible light activated photocatalysis. A comparison of the photocatalytic efficiencies of bare and nonmetal ion doped mesoporous TiO2 with/without-hierarchically 3D dendrimeric architectures was studied. The resultant photocatalytic performance of TiO2 based samples was improved greatly by nonmetal doping treatment. Meanwhile, the mesoporous TiO2 based materials with hierarchically 3D dendrimeric architecture present superior photocatalytic activity compared to the one without hierarchical structure.

Key words: Titania, 3D dendrimental nanostructure, Nonmetal doping, Visible light photocatalyst
