摘要
光催化技术是解决当今人类社会中环境问题和能源危机两大问题的有效方式,开发高效的光催化剂成为本领域研究的热点。碳量子点是一种新型碳纳米材料,因其独特的上转换发光特性和优异的光生电子传递特性,在光催化领域受到广泛关注和研究。介绍了光催化降解污染物的机理,碳量子点的性能,着重综述了碳量子点在光催化降解水环境中有机污染物的研究进展,探讨了碳量子点在光催化降解中的研究目前存在的问题及未来的发展方向。
Photocatalytic technology is an effective way to solve the two major problems of environmental problems and energy crisis.The development of efficient photocatalysts has become a research hotspot in this field.As new type of carbon nanomaterial,Carbon quantum dots(CQDs)have garnered much attention in the field of photocatalysis because of their unique up-conversion luminescence and excellent photogenerated electron transfer properties.In this paper,the mechanism of photocatalytic degradation of pollutants and the properties of carbon quantum dots was introduced,the research progress of photocatalytic degradation of organic pollutants in water by carbon quantum dots was reviewed with emphasis,followed by an outlook on their future and potential development.
