摘　　要：以硫酸铜为铜源,氢氧化钠为沉淀剂,乙醇-水溶液为分散体系,通过一步沉淀制备得到氧化铜晶体。并以紫外光照时间、pH值、亚甲基蓝浓度为基础,研究了氧化铜光催化剂对亚甲基蓝的催化活性。结果表明,紫外光照120min,pH值为9时亚甲基蓝降解率最高。The copper oxide crystals were prepared by one step precipitation, for which copper sulfate, sodium hydroxide and ethanol water solution were used as copper source, precipitant and dispersion system respectively. The catalytic activity of copper oxide to methylene blue depending on factors such as ultraviolet illumination time, pH value and concentration of methylene blue was researched. The results showed that the maximal degradation of methylene blue was obtained at the conditions of ultraviolet illumination for 120 min, pH 9 and methylene blue concentration as 2 mg / L.
