(A) Photocatalytic degradation of 2, 4-dichlorophenol by different photocatalysts under visible light irradiation: Bi2S3 (a), In-Bi-10 (b), In-Bi-30 (c), In-Bi-50 (d) In2S3 (e). C and C0 are the initial concentration after the equilibrium adsorption and the reaction concentration of 2, 4-dichlorophenol, respectively. (B) Schematic illustration showing the reaction mechanism for photocatalytic degradation of organic pollutants over the Bi2S3/In2S3 core/shell composite.
