摘要
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,H_(2)O_(2)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%。
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 H_(2)O_(2) concentration at 16 mmol/L,the degradation rate of the PAM in 100 mg/L PAM solution(initial mass concentration)could reach 99.30%.
