摘　　要：采用水热法制备NiO纳米薄片,用XRD和TEM对样品的晶型及颗粒形貌进行了表征。以蒽醌染料B-RN为对象,紫外灯为光源,研究了催化剂热处理温度、催化剂用量、光照时间、染料的初始浓度等因素对染料脱色率的影响,以及催化剂的重复利用。结果表明:NiO薄片催化剂能显著的降解蒽醌染料B-RN,且能重复利用。NiO nanosheets were prepared by hydrothermal method, with analysis of its microstructure and morphology by XRD and TEM. Photocatalytic degradation of B -RN solution was studied with NiO nanosheets as catalyst agent under UV lamp. The effect of roasting temperature of catalyst, irradiation time, catalyst dosage, initial concentration of B-RN and used amount of catalyst on decolorization was also investigated. Results showed that NiO nanosheets can degrade B-RN solution effectively, with easy reuse.
