Preparation, activity, and mechanism of ZnIn2S4-based catalysts for photocatalytic degradation of atrazine in aqueous solution

Abstract Atrazine in aquatic environment poses a potential threat to human health and ecological system, and photocatalytic technology exhibits a promising prospect for eliminating trace pollutants in water. Four photocatalysts, ZnI2S4 (ZIS) and other three ZIS-based catalysts, g-C3N4/ZIS (CZIS), BiOBr/ZIS (BZIS)and Pd-ZIS (PZIS), were prepared by a facile hydrothermal method and characterized by BET, UV–vis DRS, SEM, TEM, XRD and XPS, respectively. It showed that four catalysts had high photocatalytic activities for atrazine degradation under different light sources irradiation, and their active sequence was PZIS
