摘　　要：用均相沉淀法合成了不同粒径和形状的镍的氧化物,通过XRD、TG-DTA对产物进行了物相及热稳定性分析,研究了镍的氧化物作为光催化剂降解脱色染料废水的效果,比较了不同粒径和形状的镍的氧化物的光催化性能。实验结果表明NiO具有良好的光催化性能。NiO was prepared by chemical coprecipitation . The crystal structure, particle-size, and morphology of NiO were analyzed by TG-DTA ,XRD. The efficiency of decolorization of dye waste water by NiO was studied. The relations of their structure and the photocatalytic activity were discussed. The results showed that NiO had good photocatalytic activity .
