SrTiO3/g-C3N4/Bi2O3复合物的可见光催化性能
Photocatalytic Activity of SrTiO3/g-C3N4/Bi2O3Ternary Composite
摘要
Abstract
SrTiO3/g-C3N4/Bi2O3composite photocatalysts were prepared by a mixing-calcination method with pre-synthesised SrTiO3, g-C3N4and Bi(NO3)3·5H2O. The structure and morphology of the prepared SrTiO3/g-C3N4/Bi2O3 sample were characterized, and the effect of Bi(NO3)3·5H2O dosage on the structure and photocatalytic activity was also investigated. The results show that there exists a heterojunction in the ternary composite, leading to the acceleration of the electron?hole separation and the enhancement of photocatalytic activity. The photocatalytic activity of SrTiO3/g-C3N4/Bi2O3(at a molar ratio of SrTiO3:g-C3N4:Bi(NO3)3·5H2O of 4:6:1) for NO removal rate is 53.2％ in 30 min.关键词
