Copper hydroxide nitrate (Cu(2)(OH)(3)NO(3)) was synthesized solvothermally in anhydrous ethanol and characterized by XRD, FTIR, TG-DTA and SEM. The peroxide degradation of an azo dye (Direct Blue 15) on this material was evaluated by examining catalyst loading, initial pH, hydrogen peroxide dosage, initial dye concentration and temperature. The leaching of Cu from the copper hydroxide nitrate during the reaction was also measured. The copper hydroxide nitrate synthesized solvothermally, which was of a novel spherical morphology with complex secondary structures and contained high-dispersed Cu(2)O impurity, showed good performance for oxidation degradation of the azo dye, especially high catalytic activity, high utilization of hydrogen peroxide and a wide pH range, whereas the copper hydroxide nitrate synthesized by the direct reaction of copper nitrate and sodium hydroxide showed low catalytic activity.
碱式硝酸铜（Cu(2)(OH)(3)NO(3)）采用溶剂热法在无水乙醇中合成，并通过 XRD、FTIR、TG-DTA 和 SEM 进行了表征。通过考察催化剂负载量、初始 pH 值、过氧化氢用量、初始染料浓度和温度，评估了该材料对过氧化物的偶氮染料（直接蓝 15）的降解性能。还测量了反应过程中碱式硝酸铜中铜的浸出情况。采用溶剂热法合成的碱式硝酸铜具有新颖的球形形态，具有复杂的二级结构，含有高分散的 Cu(2)O 杂质，对偶氮染料的氧化降解表现出良好的性能，特别是具有高催化活性、高过氧化氢利用率和宽 pH 范围，而由硝酸铜和氢氧化钠直接反应合成的碱式硝酸铜则表现出低催化活性。
