摘　　要：作为全球消耗量最大的塑料之一,PET(聚对苯二甲酸乙二醇酯)在食品包装、饮料瓶、纺织品、建筑等领域得到广泛应用。然而,PET不断增长的废弃物排放给环境可持续发展带来压力。与焚烧或降解为CO_(2)的技术相比,将PET氢解为化工原料并实现高值利用的催化氢解技术近年来受到关注。该技术可在实现废弃物资源化利用的同时带来经济效益。目前,催化氢解技术尚未投入工业应用,其面临的主要挑战在于关键催化材料的催化性能和制备成本。因此,发展高性能催化剂是实现催化氢解技术工业应用的关键。文章综述了PET催化氢解技术的发展现状,特别是关键催化材料的研究进展,归纳了主要催化剂的设计策略,在此基础上探讨了高效PET催化氢解材料的未来发展方向,以期为PET催化氢解技术的进一步发展提供支持。As one of the largest consumed plastics in the world,PET(polyethylene terephthalate)is widely used in food packaging,beverage bottles,textiles,construction and other fields.However,the continuous increase in PET waste emissions also poses problems for sustainable environmental development.Compared with technologies such as incineration or degrading PET into CO_(2),catalytic hydrogenolysis technology which depolymerizes it into high-value chemical raw materials,has received much attention in recent years.This technology can bring economic benefits while realizing waste recycling.Currently,the catalytic hydrogenolysis technology has not been put into industrial use,and the main challenges come from the catalytic performance and preparation cost of key catalytic materials.Therefore,the development of low-cost and high-performance catalysts is the key to the industrial application of this technology.This article summarizes the research progress of PET catalytic hydrogenolysis,catalyst design strategies with practical application potential,and points out the possible development direction of PET high-efficiency catalytic hydrogenolysis technology in the future.It is believed that this paper is of great significance for promoting its development and industrial application.
