Preparation and photocatalytic activity of TiO2/CeO2/Bi2O3 composite for Rhodamine B degradation under visible light irradiation.

Highlights: [•] A material library of TiO2/CeO2/Bi2O3,which consists of 66 samples, is designed. [•] Ball milling and sintering are used to obtain TiO2/CeO2/Bi2O3 composite material. [•] The photocatalytic efficiencies of the samples are evaluated upon visible light. [•] The best sample, which the ratio of TiO2/CeO2/Bi2O3 is 2/5/3, is screened out. [ABSTRACT FROM AUTHOR]
