中文摘要:
      以醋酸铜 Cu(Ac)2 和硫化钠(Na2S)以及氧化石墨烯 (GO) 为原料,去离子水作溶剂,十六烷基三甲基溴化铵 (CTMAB) 为表面活性剂,在水热条件下合成CuS/GO纳米复合材料。并对其进行了XRD,FT-IR,XPS,SEM和 TEM 表征,发现具有10~20nm左右CuS纳米粒子均匀的负载在氧化石墨烯上。CuS/GO纳米复合材料在可见光照射下对有机物四环素(TC)和罗丹明B (Rh-B)表现优异的光催化活性,在可见光照射120分钟后分别对TC和Rh-B降解速率达到63%和85%。通过-ln(C/C0) 对反应时间呈现线性关系说明样品在降解TC和Rh-B过程遵循一级动力学原理。
英文摘要:
      A CuS/grapheneoxide nano-composite was prepared by using Cu(Ac)2, Na2S and graphene oxide (GO) as main raw materials under hydrothermal condition in present of cetyl trimethyl ammonium bromide(CTMAB), with deionized water as solvent. The sample was characterized by XRD,FT-IR,XPS,SEM and TEM. Eventually, the nanoparticles consisting of 10~20 nm CuS in situ grow on GO. The photocatalytic property of title nano-composite is investigated. The degradation ratio of tetracycline (TC) and rhodamine B (Rh-B) reach 63% and 85% after 120 min (under visible light). The result suggests that the CuS/GO nanocomposite exhibits excellent photocatalytic activity and potential application in the degradation of organic of TC and Rh-B in the pollute water. A linear relation of -ln(C/C0) vs. reaction time was obtained, suggesting that the reaction can be considered as a pseudo-first-order reaction.
