摘　　要：依据科研成果设计了复合光催化材料降解有机污染物的综合化学实验。采用简单溶剂热合成法制备了NH_(2)-MIL-53(Fe)/GO复合光催化材料,并对其进行了表征;以罗丹明B(RhB)为目标污染物,考察了复合材料光催化降解性能。结果表明,在可见光照射120 min后,复合光催化材料对RhB的降解率达到91.2%,循环使用5次后,RhB的降解率为78.3%,具有较高的光催化活性和稳定性。该实验利用可见光光催化降解环境中有机污染物,有效扩展了光催化材料的光响应范围。同时,实验内容涉及四大基础化学实验,实现了实验内容的全面融合,满足了综合化学实验要求。Based on the scientific research results,a comprehensive chemical experiment for the degradation of organic pollutants by composite photocatalytic materials is designed.The NH_(2)-MIL-53(Fe)/GO composite photocatalytic material is prepared by simple solvothermal method and characterized.The photocatalytic degradation performance of the composite material is investigated with Rhodamine B(RhB)as the target pollutant.The results show that the degradation rate of RhB by the composite photocatalytic material reaches91.2%after 120 min of visible light irradiation,and the degradation rate of RhBis 78.3%after 5 cycles,showing high photocatalytic activity and stability.In this experiment,visible light is used to photocatalytic degradation of organic pollutants in the environment,which effectively extends the light response range of photocatalytic materials.At the same time,the experimental content involves four basic chemical experiments,which realizes the comprehensive integration of experimental content and meets the requirements of comprehensive chemical experiments.
