摘要
采用直接沉淀法、微乳法及乙醇锌合成法制备了不同晶粒尺寸的ZnO纳米粒子,用XRD和TEM技术对样品进行表征.取粒径最小的纳米ZnO作光催化剂,以太阳光为光源,并以光催化降解罗丹明-B为模型反应,探讨用纳米ZnO光催化降解有机污染物的途径.
Nanocrystal ZnO particles with different size are prepared respectively by direct precipitation,microemulsion and sol-gel methods. The as-prepared samples are also characterized by techniques such as XRD and TEM. Using solar energy,the smallest ZnO nanoparticle as a photocatalyst,effective degradation of rhodamine B model pollutant is observed. Then in this way nanocrystal ZnO photocatalysis degradation of other organic pollutants is also investigated.
