摘要
采用催化剂负载到助催化剂上制得一种可以磁分离的光催化复合材料。采用湿化学法制备纳米级二硫化钼,用化学沉淀法制备球状纳米级氧化铜,通过磁力搅拌将其分散在溶有二硫化钼的去离子水中,形成含二硫化钼/氧化铜复合微粒的微乳液,经水热反应、烘干得其复合材料。采用简单的溶剂热法制备球状Fe_(3)O_(4),将所得复合材料超声处理,使其均匀分散在含四氧化三铁的悬浊液中,再经水热反应、烘干煅烧后得到纳米级磁性MoS_(2)/CuO/Fe_(3)O_(4)复合材料。通过扫描电镜、红外等手段对该磁性复合材料进行表征,复合材料具有良好的吸附性能和光催化性能,并可通过磁场进行分离和回收。
A magnetically separable photocatalytic composite material is prepared by loading a catalyst onto a cocatalyst.Nanometer molybdenum disulfide is prepared by wet chemical method,and preparation of spherical nano-sized copper oxide by chemical precipitation method.It is dispersed in deionized water containing molybdenum disulfide by magnetic stirring to form a microemulsion containing molybdenum disulfide/copper oxide composite particles.The composite material is obtained by hydrothermal reaction and drying.Spherical Fe_(3)O_(4)is prepared by a simple solvothermal method,the obtained composites material is uniformly dispersed in the suspension containing Fe_(3)O_(4)by ultrasonic treatment.After hydrothermal reaction,drying and calcination.The magnetic MoS_(2)/CuO/Fe_(3)O_(4)nanocomposites are obtained.The magnetic composite material is characterized by scanning electron microscopy and infrared spectroscopy.The composite material has good adsorption performance and photocatalytic performance,and can be separated and recovered by magnetic field.
