采用微波法制备AgInS2纳米粒子，并通过光辅助沉积法在AgInS2表面掺杂Pt。考察了AgInS2和Pt/AgInS2样品在可见光下光催化氧化氰化物的催化性能。 UV-vis 分析证明将 Pt 负载到 AgInS2 后检测到红移。在 1.5 wt% Pt/AgInS2 光催化剂下，反应时间 35 分钟后，达到的最大氧化效率为 100%。该催化剂可以重复使用，在前五个循环中不会损失任何活性。
AgInS2nanoparticles were prepared by a microwave method, while Pt was doped on the surface of AgInS2via photoassisted deposition method. The catalytic performances of the AgInS2and Pt/AgInS2samples were carried out for photocatalytic oxidation of cyanide under visible light. The UV–vis analysis proved a red shift was detected after the loading of Pt into the AgInS2. The maximum oxidation efficiency achieved was 100% at 1.5 wt% Pt/AgInS2photocatalyst after 35 min reaction time. The catalyst could be reused without any loss in activity during the first five cycles.
