摘　　要：以醋酸锌为原料,采用溶胶凝胶法制备纳米ZnO,分别以工业大麻枝叶、硫脲、尿素为碳源、硫源和氮源合成了氮硫掺杂碳量子点(N,S-CQDs),然后通过浸渍法合成了N,S-CQDs/ZnO复合材料.采用SEM,TEM,FT-IR,PL等分析方法对催化剂进行了表征.结果表明,N,S-CQDs/ZnO对染料罗丹明B(RhB)的降解效果明显高于单体S-CQDs与ZnO.Using zinc acetate as raw material,nano zinc oxide was prepared by sol gel method.Nitrogen and sulfur doped carbon quantum dots(N,S-CQDs)were synthesized by using industrial hemp leaves,thiourea and urea as carbon sources,sulfur sources and nitrogen sources respectively.Then N,S-CQDs/ZnO composites were synthesized by impregnation method.The catalyst was characterized by SEM,TEM,FT-IR and PL.The result showed that the degradation effect of N,S-CQDs/ZnO on dye rhodamineB(RhB)was significantly higher than that of monomer N,S-CQDs and ZnO.
