摘　　要：通过在石墨烯中引入内消旋-2,3-二巯基琥珀酸(DMSA)构建三维立体结构,原位合成了CdS@DMSA-GO复合材料。实验表明,反应温度对所得材料的结构和性能具有重要的影响。CdS@DMSA-GO-100℃对罗丹明B和刚果红具有最佳的吸附和光催化降解性能,降解效率可达96%以上。自由基捕获实验表明,·O2在催化过程中是主要的活性氧物质。CdS@DMSA-GO composites have been synthesized by introducing meso-2,3-dimercaptosuccinic acid(DMSA)into grapheme oxide to construct three-dimensional architecture.The experimental results indicate that the temperature has an important influence on the structure and properties of the as-prepared materials.CdS@DMSA-G-100℃exhibited the best adsorption ability and photocatalytic activity for the degradation of rhodamine B(RhB)and Congo Red(CR).The degradation rate reached over 96%.The radical trapping test illuminate that·O2 radical was the dominant active oxygen species in the photocatalytic process.
