The upcycling of plastic waste through electrochemistry has garnered significant interest. In this study, we present a two-step strategy for synthesizing boron (B) and phosphorus (P) co-doped quaternary PdRhBP nanosheets (PdRhBP NSs) aimed at converting polyethylene terephthalate (PET) plastic hydrolysate (ethylene glycol) into high-value-added chemicals. The electrocatalytic performance of PdRhBP NSs for ethylene glycol (EG) oxidation surpasses that of PdRh nanosheets (PdRh NSs) and commercial Pd black. Notably, the highest contents of glycolic acid (GA) and formate are observed at a voltage of 0.755 V. This can be attributed to the two-dimensional structural advantages of PdRhBP NSs and the synergistic effect of B and P, optimizing the electronic configuration of Pd. This study not only proposes a double-doping strategy for designing efficient electrochemical conversion catalysts but also presents a green and sustainable approach for upgrading and utilizing plastic waste.

二元非金属硼和磷共掺杂到 PdRh 纳米片中可促进聚对苯二甲酸乙二醇酯的电升级

通过电化学对塑料废物进行升级回收引起了人们的极大兴趣。在这项研究中，我们提出了一种两步合成硼（B）和磷（P）共掺杂四元PdRhBP纳米片（PdRhBP NSs）的策略，旨在将聚对苯二甲酸乙二醇酯（PET）塑料水解产物（乙二醇）转化为高价值-添加化学物质。 PdRhBP NSs 对乙二醇（EG）氧化的电催化性能超过了 PdRh 纳米片（PdRh NSs）和商用钯黑。值得注意的是，在 0.755 V 电压下观察到乙醇酸 (GA) 和甲酸盐的含量最高。这可归因于 PdRhBP NSs 的二维结构优势以及 B 和 P 的协同效应，优化了 PdRhBP NSs 的电子构型。博士。这项研究不仅提出了设计高效电化学转化催化剂的双掺杂策略，而且提出了一种升级和利用塑料废物的绿色可持续方法。
