Method for driving anthraquinone and derivatives thereof to catalyze degradation of organic pollutants by visible light

The invention relates to the technical field of photocatalytic degradation of organic pollutants, and discloses a simple, efficient and green method for driving anthraquinone and derivatives thereof to catalyze degradation of organic pollutants by visible light. Under the normal-temperature and normal-pressure oxygen-containing atmosphere condition, 50 mg/L of rhodamine B can be efficiently degraded within 30 min through the method, and the degradation efficiency of rhodamine B can be remarkably improved with 0.5 mmol/L hydrochloric acid as an additive. Moreover, the method shows good applicability in degradation of organic pollutants such as methyl orange, methylene blue and tetracycline, and is expected to provide a new idea for photodegradation of the organic pollutants. 本发明涉及有机污染物的光催化降解技术领域，公开了一种可见光驱动蒽醌及其衍生物催化有机污染物降解的简便、高效和绿色方法。在常温常压含氧气氛条件下，该方法在30 min内能高效降解50 mg/L的罗丹明B，以0.5 mmol/L盐酸作添加剂可显著提罗丹明B的降解效率。并且，该方法在降解甲基橙、亚甲基蓝、四环素等有机污染物表现出良好的适用性，有望为有机污染物的光降解提供一种新思路。
