【摘要】 分别用均相沉淀法,溶胶-凝胶法和直接沉淀法制备了纳米级NiO粉体,用XRD和TEM对纳米NiO粉体的晶型及颗粒形貌进行了分析.研究了3种不同方法制备的氧化镍粉体光催化降解蒽醌染料B-RN废水的效果及影响光催化性能的因素;结果表明:均相沉淀法制备的氧化镍粉体颗粒均匀、粒径小、光催化性能最好.更多还原

【Abstract】 NiO nanopowders were prepared by homogeneous precipitation method,sol-gel,precipitation method,and characterized by XRD and TEM for obtaining the crystal types and the morphology.Investgate the effect of degradation of Anthraquinone B-RN dye in waste water with NiO nanopowders,which prepared with different methods.The result indicated that NiO nanopowders prepared by the homogeneous precipitation method have uniform grain,small grain size and the best photocatalytic capacity.更多还原
