摘　　要：以氧化镍的光催化效率为评价标准,采用乳状液膜法制备氧化镍,以其为催化剂,在磁场强化条件下光催化降解亚甲基蓝溶液,研究其光催化性能。研究发现,在乳液静置时间为1h、提取搅拌时间为15min、煅烧温度为700℃、煅烧时间3h、氢氧化钠浓度为0.3mol/L的条件下,制成的镍基氧化物光催化剂性能良好,在磁场强度为1.5T的磁场下磁化2h,然后进行光催化实验100min,去除率可达90.68%。通过XRD图谱显示,煅烧温度影响氧化镍粉体结构,同时影响其光催化效果。Taking the photocatalytic efficiency of nickel oxide as the evaluation standard,the nickel oxide was prepared by emulsion liquid membrane method.And as a catalyst,Photocatalytic degradation of methylene blue solution under magnetic field enhancement,its photocatalytic performance is studied.The study found that the performance of nickel-based oxide photocatalyst was obtained under the conditions of emulsion rest time of 1 h,extraction and stirring time of 15 min,calcination temperature of 700℃,calcination time of 3 h,and sodium hydroxide concentration of 0.3 mol/L.The prepared nickel-based oxide photocatalyst has good performance,magnetized for 2 h under a magnetic field of 1.5 T,then carries out the photocatalysis experiment for 100 min,the removal rate can reach 90.68%.Displayed by XRD pattern,the calcination temperature affects the structure of the nickel oxide powder and affects its photocatalytic effect.
