Abstract
Titania photo-catalyst was prepared via hydrothermal synthesis route from industrial titanyl sulfate solution, and the effects of calcination temperature on the structure and property of porous were also investigated. The as-prepared samples were characterized by XRD and BET, and its photocatalytic activity was evaluated by photocatalytic degradation of methylene blue. As the calcination temperature increasing, the photocatalytic degradation rate increased first and then gradually decreased. Titania calcined at 450°C for 1h shows the highest photocatalytic activity, with degradation rate of 88% for 1h. And its SBETis of 93.25 m2/g, crystal size of 17.19 nm.
