聚酯/聚醚类塑料（如聚对苯二甲酸乙二醇酯PET、聚乳酸PLA、聚乙二醇PEG、聚苯醚PPO等）大量废弃引发严重环境问题，电催化升级回收有望在温和条件下将其转化为高值化学品，其核心是催化剂设计。本文从电子结构调控、形貌调控、界面电荷转移调控及电解液环境调控等四个方面，系统综述了该领域催化剂设计的最新进展。催化剂设计中，电子结构调控可通过杂原子掺杂、缺陷工程及配体配位等优化活性中心电子结构与吸附行为；形貌调控可借助多维纳米结构增强传质与活性位点暴露；界面电荷转移调控可利用异质结、肖特基结等加速电子迁移；电解液环境调控可通过pH离子种类及界面微环境工程调控反应路径。进一步的研究工作中，利用原位表征技术解析催化机制及微观反应路径，结合机器学习加速催化剂筛选，建立聚酯/聚醚类塑料电催化回收用催化剂体系构效关系，可望显著推进废弃聚酯/聚醚电化学升级回收的基础研究和实际应用。

Polyester/polyether plastics (such as polyethylene terephthalate PET, polylactic acid PLA, polyethylene glycol PEG, polyphenylene oxide PPO, etc.) that are extensively discarded have caused serious environmental problems. Electro-catalytic upcycling has the potential to convert them into high-value chemicals under mild conditions and the catalyst design is the key. This article systematically reviews the latest progress in catalyst design in this field from four aspects of electronic structure regulation, morphology regulation, interface charge transfer regulation, and electrolyte environment regulation. In catalyst design, electronic structure regulation can optimize the electronic structure and adsorption behavior of active centers through doping of heteroatoms, defect engineering, and ligand coordination; morphology regulation can enhance mass transfer and the exposure of active sites by multi-dimensional nanostructures; interface charge transfer regulation can accelerate electron migration through heterojunctions and Schottky junctions; electrolyte environment regulation can control reaction pathways through pH ion types and interface microenvironment engineering. In further research work, using in-situ characterization techniques to analyze the catalytic mechanism and microscopic reaction pathways, combined with machine learning to accelerate catalyst screening, to establish the structure-activity relationship of catalyst systems for electro-catalytic upcycling of polyester/polyether plastics, is expected to significantly advance the basic research and practical application in this field.
