摘要
SrTiO3/g-C3N4/Bi2O3 composite photocatalysts were prepared by a mixing-calcination method with pre-synthesised SrTiO3, g-C3N4 and 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. © 2017, Editorial Department of Journal of the Chinese Ceramic Society.
