易回收型光催化材料降解水体污染物的研究进展

Research Progress of Recyclable Photocatalysts for Pollutants Degradation in Water

环境污染和能源危机在全球范围内日益严峻,光催化技术作为一种性能优良、节能、反应条件温和的环境净化技术,在降解水体污染物中展现出潜在的应用前景。但传统粉末状的光催化剂带来的难回收、易消耗、可能存在二次污染等问题限制了其实际应用。因此,本文基于5种不同类型的载体,综述了近年来国内外易回收型光催化材料的发展现状,并对其未来发展趋势进行了展望。

Environmental pollution and energy crisis are getting more and more serious over the world.As an environmental purification technology,photocatalysis with excellent performance,energy-saving and mild reaction conditions,has shown a potential application prospect in degrading water pollutants.However,the traditional powder-shaped photocatalysts are difficult to recycle,easy to consume and may have secondary pollution,which limits their practical application.Therefore,this paper introduces the development status of recyclable photocatalyst based on five different types of carriers,and looks forward to the future development trend.
