ZnS/CuS/RGO复合材料的制备及其对聚丙烯酰胺的光催化降解性能

采用水热合成法制备了Zn/Cu-MOFs（金属有机框架化合物）/GO（氧化石墨烯）复合材料，将其与硫代乙酰胺（TAA）反应制备出ZnS/CuS/RGO（还原氧化石墨烯）异质结复合材料，利用扫描电子显微镜、X射线衍射仪、荧光分光光度计等对ZnS/CuS/RGO复合材料进行了表征，并在太阳光下，考察了其对聚丙烯酰胺（PAM）的光催化降解性能。结果表明:在锌铜比（摩尔比）为1∶9，ZnS/CuS/RGO加入质量浓度为0.5 g/L，H2O2加入浓度为16 mmol/L的条件下，可使初始质量浓度为100 mg/L的PAM溶液的PMA降解率达到99.30%。

Preparation of ZnS/CuS/RGO composites and their photocatalytic degradation performance on polyacrylamide

The Zn/Cu-MOFs（metal organic framework）/GO（graphene oxides） composites were prepared by hydrothermal synthesis，then the ZnS/ Cus/RGO（reduced graphene oxide） heterojunction composites were prepared by reacting the above prepared composites with thioacetamide. The ZnS/CuS/RGO composites were characterized by scanning electron microscope， X-ray diffraction and fluorescence spectrophotometer， and their photocatalytic degradation performance on polyacrylamide（PAM） was investigated under the simulated sunlight. The results showed that under the conditions of Zn/Cu molar ratio at 1∶9，ZnS/CuS/RGO mass concentration at 0.5 g/L and H2O2 concentration at 16 mmol/L， the degradation rate of the PAM in 100 mg/L PAM solution（initial mass concentration） could reach 99.30%.
