Study on photocatalytic activity of TiO2 catalyst co-doped with boron, nitrogen and cerium
|
Abstract:
The titania photocatalyst co-doped with boron, nitrogen and cenum was prepared by the sol-gel method. The catalyst was characterized by XRD and SEM. The photocatalytic activities were evaluated by the degradation of acid scarlet dye, and the relationships between the preparation conditions and the activities of co-doped TiO_2 were investigated. The results showed that the degradation rate of acid scarlet dye reached up 98% when the atomic ratio among B, N and Ti was 1:2: 0. 1, calcined 400 ℃ for 3 h.
