摘要： 氧化亚铜的光降解成为当前国内外研究的热点之一。笔者主要通过自制的微纳米氧化亚铜为催化剂，以甲基橙模拟印染废水进行光降解研究，通过吸光度评价降解效率。实验探究了氧化亚铜的形貌、粒径、用量以及使用频率等因素的改变对光降解效果的影响。结果表明，当2 μm球形微米氧化亚铜用量1.2 g/L，甲基橙初始质量浓度为20 mg/L时，经过16 h无阳光直射条件下，测得的降解率最高可达90%。实验还进一步发现，添加纤维素载体不仅能够减少光催化剂团聚，而且方便回收。

Abstract: The issue of printing and dyeing wastewater limited China’s printing industry. The recent researches were focused on photocatalysis of the semi-conductive materials like Cu2O. A serial of Cu2O were prepared by one-step reduction reaction. Then, the degradation experiments were carried out by changing the conditions like the Cu2O morphology, particle size, quantity, the reuse, etc. Last, the paper disclosed that the optimistic rate degradation of methylene orange (20 mg/L) was more than 90% during 16 hours without direct-sunlight and other extra-fixings. And the prospective catalytic concentration was 1.2 g/L, as soon as particle size, morphology was 2 μm and spherical morphology, respectively. At the same time, the matter of particles aggregation and reused were resolved by adding hydroxypropyl methylcellulose as matrix materials.
