Preparation and photocatalytic activity of titanium oxide anchored on the channel surface of nanoporous material VSB-1

摘要

The nanosized TiO_2 particles anchored on the channel surface of nanoporous nickel phosphate VSB-1 with a low coverage of 1.23 wt. percent have been first reported. XRD, EDX, FTIR, UV-Vis, and N_2 adsoiption analyses showed that nanosized TiO_2 particles were in the channels or pores of VSB-1. The photocatalytic activity studies showed that the TiO_2-anchored VSB-1 (TiO_2-VSB-l) material had higher activity (64.51 percent) for phenol degradation than that of 46.94 percent for the corresponding pure bulk TiO_2 in 4 h.
