摘要 光催化降解是一种有效降解罗丹明B的方法,为环境保护和人类健康做出了巨大的贡献,因此其具有广泛的应用前景.采用改良的Hummers法制备氧化石墨烯(GO),在此基础上,采用水热合成法制得硫化铜/氧化石墨烯(CuS/GO)纳米复合材料.通过傅里叶红外(FITR)、X-射线衍射仪(XRD)、透射电子显微镜(TEM)、X-射线光电子能谱仪(XPS)等对复合材料进行表征.结果表明,随着醋酸铜含量的增加,负载在GO的CuS纳米粒子的量也随之增加,同时粒子尺寸也发生了变化.当醋酸铜含量占35.9%时,复合材料中CuS纳米粒子为3 nm,其形貌良好,负载均匀,且CuS的尺寸较小.CuS/GO复合材料对罗丹明B表现出了良好的光催化活性.
