摘要
以CuSO4.5H2O和氢氧化钠为原料、葡萄糖为还原剂、乙二醇为溶剂,通过溶剂热法合成了纳米Cu2O,并用透射电子显微镜(TEM)及X射线衍射(XRD)对其进行了表征;以所合成Cu2O为催化剂,在避光无搅拌的环境下,对其降解亚甲基蓝的性能进行了研究,得到最优催化条件:催化剂用量0.400 g/L,双氧水用量2.5mL(质量分数为12.63%),亚甲基蓝初始质量浓度为10 mg/L时降解效果最佳,50 min后降解率达到95%以上.
The nanocrystalline Cu2O was prepared by the solvothermal method using CuSO4·SH2O and NaOH as the starting materials and glucose as the reducing agent. The as-preraed Cu2O was characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The degradation of methylene blue in Cu2O suspension without lights and stirring is investigated, the rate of degradation is more than 95% after 50 min in the best catalytic condition : Cu2O( 0.400 g/L), H2O2( 2.5 mL, 12.63% ), the initial methylene blue concentration( 10 mg/L ).
