Abstract

The electrocatalytic transformation of polyethylene terephthalate (PET) plastic to valuable products represents highly promising strategy for the re-utilization of waste resources, and its efficiency is highly related to the identification of active and selective electrocatalysts. Herein, high-entropy PdPtSnBiAg metallene (HEA-PdPtSnBiAgene) is designed via a solvothermal method as an efficient electrocatalyst for PET-derived ethylene glycol oxidation reaction (EGOR). In PET hydrolysate, the HEA-PdPtSnBiAgene exhibits high Faraday efficiency of 91.8% at 0.91 V, as well as excellent cycle stability.Both experimental investigations and theoretical analyses support that the synergistic electronic effect of HEA-PdPtSnBiAgene provides multi-level active sites, which can reduce EGOR energy barrier and strengthen the C-C and O-H bond energy of EG, thus promoting the EG-to-GA conversion. This research contributes to advanced insights to develop unique high-entropy metallene for electrochemical upcycling of PET plastic.

高熵PdPtSnBiAg金属烯在PET塑料电化学重整制乙醇酸中的协同电子效应

聚对苯二甲酸乙二醇酯（PET）塑料的电催化转化为有价值的产品是一种非常有前途的废物资源再利用策略，其效率与活性和选择性电催化剂的识别高度相关。本文采用溶剂热法设计了高熵PdPtSnBiAg金属烯（HEA-PdPtSnBiAgene）作为pet衍生乙二醇氧化反应（EGOR）的高效电催化剂。在PET水解物中，HEA-PdPtSnBiAgene在0.91 V下具有91.8%的法拉第效率，并且具有良好的循环稳定性。实验研究和理论分析均支持HEA-PdPtSnBiAgene的协同电子效应提供多级活性位点，降低EGOR能垒，增强EG的C-C和O-H键能，从而促进EG向ga的转化。该研究为开发用于PET塑料电化学升级回收的高熵金属烯提供了新的思路。
