中文摘要: 本文利用一步溶剂热法制备CulnS2可见光光催化剂,运用XRD、SEM、BET等对材料进行表征分析。探究了前驱液Cu/ln摩尔比、温度、时间和捕获剂种类对CulnS2在可见光下光催化还原溶液中U(VI)的性能。研究结果表明:当Cu:ln=1:1,样品制备温度为200℃,制备时间为12h的条件下,所制备的CulnS2材料光催化还原U(VI)活性最佳,光催化还原过程的主要活性物质是O2-和e-
Abstract:Vsible light photocatalyst CulnS2 material was prepared by one-step solvothermal method. the composite photocatalyst was Characterized and analyzed the material with XRD, SEM, BET. TheSeffectsSofSCu/ln molar ratio, temperature, time and trapping agent types of precursor liquid were explored on the performance of CulnS2 photocatalytic reduction of U(VI) in solution under visible light. The results showed that Cu:ln=1:1, the sample preparation temperature is 200℃, and the preparation time is 12h, the prepared CulnS2 material has the best photocatalytic reduction activity for U(VI), and the main photocatalytic reduction process is The active substances are O2- and e-.
