Abstract

Abstract

Titania with high surface area was prepared by hydrothermal method using industrial titanyl sulfate solution as raw material. The influence of hydrothermal reaction time and calcination temperature on the specific surface area of titania were investigated. The samples were characterized by BET, XRD, XPS, SEM, TEM, FT-IR, UV-Vis DRS and the visible photocatalytic activity was evaluated by the degradation of model compound Rhodamine B. The results show that the proper hydrothermal reaction time and low calcination temperature are beneficial to the preparation of titania with high specific surface area. The titania obtained by hydrothermal reaction for 3 h and calcination temperature at 300 ℃ has the highest specific surface area, up to 214.3 m²/g. And the visible light degradation activity of Rhodamine B is significantly better than that of commercial titanium dioxide P25, which is because the prepared titania has a higher specific surface area and better visible light absorption, its degradation rate reached 90.3% in 2 h.
