Synthesis and characterization of Cd-doped ZnO nanoflowers and its photocatalytic activity

  • 摘要: 以氯化锌、氯化镉、氢氧化钠为原料,采用水热法合成Cd掺杂纳米花状ZnO光催化剂,并通过该样品对罗丹明B水溶液的降解来研究其光催化活性。利用X射线衍射(XRD)、扫描电子显微镜(SEM)、X射线能量色散谱(EDS)、光致发光谱(PL)及紫外-可见分光光度计(UV-Vis)等测试手段对材料物性进行表征。实验结果表明:当掺杂Cd2+时,样品形貌发生变化、粒径减小;掺杂Cd2+后的ZnO的吸收边和紫外峰对比于纯ZnO均发生红移,禁带宽度由3.24 eV 减小到3.16 eV。通过光催化实验分析可知,掺杂后纳米ZnO光催化剂对罗丹明B 水溶液的降解率有所提高,光照3 h其降解率高达98%,说明与纯ZnO相比,Cd掺杂ZnO纳米花具有更高的光催化活性。
