摘　　要：Adsorption-photocatalytic degradation of organic pollutants in water is an advantageous method for environmental purification.Herein,a feasible strategy is developed to construct a novel dual S-scheme heterojunctions Cu_(7)S_(4)-TiO_(2)-conjugated polymer with a donor-acceptor structure.There are abundant adsorption active sites for adsorption in the porous structure of the composites,which can rapidly capture pollutants through hydrogen bonding and π-π interactions.In addition,the dual S-scheme heterojunctions effectively improve carrier separation while maintaining a strong redox ability.Thus,the optimized 1.5% CST-130 catalysts can adsorb 71% of 20 ppm BPA in 15 min and completely remove it within 30 min with high adsorption capacity and photodegradation efficiency.Therefore,this study provides a new inspiration for synergistic adsorption and degradation of BPA and the construction of dual S-scheme heterojunction.
