摘　　要：以三元硝酸盐水溶液为原料,采用微乳液烧结法制备了CuFeMnO_(4)纳米材料。通过层层沉积法合成了核-壳-壳结构的CuFeMnO_(4)@SiO_(2)@TiO_(2)磁负载光催化材料。采用XRD,SEM,TEM,FT-IR,EDS和UV-Vis对制备的磁负载光催化材料进行了表征。结果表明,磁负载光催化材料为光滑球形纳米粒子,具有较好的紫外-可见吸收能力。通过光催化降解罗丹明B溶液评价其光催化活性,光照6 h,降解率达到88.9%,经5次磁回收循环降解实验,仍具有较高的光催化活性。CuFeMnO_(4)nanomaterials were prepared by microemulsion sintering method using ternary nitrate aqueous solution as raw material.CuFeMnO_(4)@SiO_(2)@TiO_(2)magnetically loaded photocatalytic material with core-shell-shell structure was synthesized by layer deposition method.The prepared magnetically loaded photocatalytic materials were characterized by XRD,SEM,TEM,FT-IR,EDS and UV-Vis.The results showed that the magnetically loaded photocatalytic material was a smooth spherical nanoparticle with good UV-visible absorption capacity.The photocatalytic activity of rhodamine B solution was evaluated by photocatalytic degradation.The degradation rate reached 88.9%under light for 6 h.After 5 magnetic recovery cycles of degradation experiments,it still had high photocatalytic activity.
