摘    要:采用水热法制备片状纳米NiO,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KN-R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效果。结果表明:NiO催化剂能显著降解蒽醌染料KN-R,且能重复利用,在未曝气供氧时,NiO的催化活性优于p-25 TiO2。

关 键 词:氧化镍  脱色  蒽醌染料KN-R  水热法  纳米薄片

Abstract:NiO nanosheets was prepared by the hydrothermal method; its microstructure and morphology were analyzed by XRD, TEM. The effect of heat treatment temperature and dosage of catalyst, time of irradiation, initial concentration of the dyestuff KN-R,and the repeated use of catalyst on decolorization rate of the dyestuffwas investigated.With authraquinone KN-R as treating object and UV lamp as irradiation source,the results showed that NiO nanosheets could degrade KN-R solution effectively;the catalyst could be used repeatedly;and its photocatalytic activity is better than that of p-25 TiO2 in the same conditions.
Keywords:NiO  decolorization  Anthraquinone dye KN-R  hydrothermal method  nanosheets
