摘要
随着塑料污染的日益严重和人们对可持续发展的日益重视,废塑料的升级和回收利用已成为一项重要任务。在本研究中,构建了具有镧系收缩效应的有机配体修饰的PdPr纳米片(PdPr O - NSs),并将其用作聚对苯二甲酸乙二醇酯增值转化的高性能电催化剂。PdPr O‐NSs只需要0.75 V的电位就可以提供200 mA cm−2的电流密度。在0.675 V下,产物乙醇酸的法拉第效率和选择性分别达到97.5%和94.6%。密度泛函理论计算证实,Pr和正辛酸的存在调节了电子结构和配位环境,提高了电子传递效率和催化性能。这项工作不仅为构建新型高效镧系掺杂纳米电催化剂提供了新的策略,而且为废塑料的回收利用铺平了道路。
Lanthanide contraction effect of PdPr nanosheets boosting PET electrocatalytic value‐added conversion
With the worsening of plastic pollution and increasing attention being paid to sustainable development, the upgrading and recycling of waste plastics have become important tasks. In this study, organic ligand‐modified PdPr nanosheets (PdPr O‐NSs) with the lanthanide contraction effect are constructed and used as high‐performance electrocatalysts for the value‐added transformation of polyethylene terephthalate. PdPr O‐NSs only require a potential of 0.75 V to supply current densities of 200 mA cm−2. The Faraday efficiency and selectivity for the primary product glycolic acid reached 97.5% and 94.6% at 0.675 V, respectively. Density functional theory calculations confirm that the existence of Pr and n‐octanoic acid adjusts the electronic structure and coordination environment, improving the electron transfer efficiency and catalytic performance. This work not only provides a new strategy for constructing novel and efficient lanthanide‐doped nanomaterial electrocatalysts but also paves the way for recycling waste plastics.
