Publication date: 25 November 2018Source: Journal of Industrial and Engineering Chemistry, Volume 67Author(s): Huiqin Wang, Dongyao Wu, Chongyang Liu, Jingru Guan, Jinze Li, Pengwei Huo, Xinlin Liu, Qian Wang, Yongsheng YanAbstractThe purpose of this work designed hybrid-structured and plasma effect photocatalyst of Ag/In2O3/TiO2/HNTs via sol–gel and photo-reduction methods. The structures, morphologies, optical and photoelectric performances of as-prepared photocatalysts were characterized via XRD, TEM, XPS, BET, UV–vis DRS, PL and photocurrents. The photocatalytic activity was evaluated by degradation of TC. The results showed that the hybrid-structure and plasma effect can effectively cause the multi-transfer of electrons and increase the separation rate of electron and hole pairs which obtained high photocatalytic activity. The photocatalytic degradation processes reveal that O2− and h+ are major active species.Graphical abstract
