为减轻塑料废弃物所带来的环境污染,对塑料光催化降解回收处理方式进行研究,从而利用太阳能光引发和光催化的降解机理将塑料转化为水和二氧化碳或进一步转化为氢气燃料和高值化学品.文章介绍催化剂特性、塑料和降解条件对光催化降解的影响,总结不同种类的无机金属、非金属材料以及有机-无机复合材料光催化剂在光催化降解回收处理中的应用,旨在通过催化剂的改性、与电催化、热催化、生物催化协同作用提升光催化效率.文章指出光催化降解塑料回收处理技术在预处理、处理后存在的问题,为废弃塑料的回收处理提供可靠依据和研究方向.
Research Progress of Photocatalytic Degradation and Recycling of Plastics
In order to reduce the environmental pollution caused by plastic waste,research is being conducted on the photocatalytic degradation and recycling of plastics,utilizing the degradation mechanism of solar photoinitiation and photocatalysis to convert plastics into water and carbon dioxide,or further into hydrogen fuel and high-value chemicals.The article introduces the effects of catalyst characteristics,plastics,and degradation conditions on photocatalytic degradation,summarizes the applications of different types of inorganic metal,non-metal materials,and organic-inorganic composite photocatalysts in photocatalytic degradation and recycling,and aims to improve photocatalytic efficiency through catalyst modification and synergistic effects with electrocatalysis,thermocatalysis,and biocatalysis.The article points out the problems in the pre-treatment and post-treatment of photocatalytic degradation plastic recycling technology,providing a reliable basis and research direction for the recycling and treatment of waste plastics.
