ZnS-In2S3制備及其可見光催化性能與生物毒性研究ZnS-In2S3制備及其可見光催化性能與生物毒性研究

摘要：

本文研究了ZnS-In2S3復(fù)合材料的制備方法，通過不同合成方法和合成條件的調(diào)節(jié)，得到了不同形貌和結(jié)構(gòu)的復(fù)合材料，并對其在可見光條件下催化降解有機污染物的性能進(jìn)行了研究。結(jié)果表明，ZnS-In2S3復(fù)合材料具有較高的催化性能和穩(wěn)定性，其中以化學(xué)共沉淀法得到的納米片狀復(fù)合材料表現(xiàn)出最佳的催化性能，可在可見光照射條件下高效降解有機染料。此外，本文還對ZnS-In2S3復(fù)合材料的生物毒性進(jìn)行了研究，結(jié)果表明，在一定濃度范圍內(nèi)，復(fù)合材料對水生生物的毒性較小，且對菜豆種子生長的影響也較小，表明其具有較好的生物相容性，可作為一種環(huán)境友好型的催化劑材料。
