Porous TiO2 photo-catalyst is prepared via hydrothermal synthesis route from industrial titanyl sulfate solution,and the effects of calcination time on the structure and property of porous TiO2 are also investigated.The as-prepared samples are characterized by XRD,SEM,XPS,FT-IR and BET,and their photocatalytic activities are evaluated by photocatalytic degredation of methylene blue.As the increase of calcination time,the photocatalytic degradation rate increases at first and then gradually decreases.Porous titania calcined at 500℃ for 1 h shows a lowest photocatalytic activity,with a degradation rate of 88%,SBET of 61.49 m2/g and crystal size of 16.10 nm.
