摘要
聚对苯二甲酸乙二醇酯（PET）是一种广泛使用的塑料；然而，它不容易降解。实际上，由PET水解产物得到的乙二醇（EG）可以电催化氧化为高附加值的甲酸（FA）；电催化剂的设计是关键问题。然而，传统催化剂存在成本高、活性单一、裂解水电压高、法拉第效率低的问题。本文制备了V掺杂Ru/RuP4 Mott-Schottky （M - s）异质结，10%V-Ru/RuP4具有最宽的带隙和对EG氧化反应（EGOR）的良好敏感性，在1 M KOH + 0.3 M EG中，EGOR电压为1.05 V, 10 mA cm-2，电催化性能优异。同时，10%V-Ru/RuP4具有良好的析氢反应性能，在10 mA cm-2下的析氢电位为119 mV。此外，在1.5 V电压下，EG经93.9%的高FE电催化氧化为FA。这项工作提供了一个特殊的M-S异质结PET降解和升级循环与氢的演化。
Polyethylene terephthalate (PET) is a widely used plastic; however, it is not easily degraded. Actually, the ethylene glycol (EG) derived from PET hydrolysate can be electrocatalytically oxidized to high-value-added formic acid (FA); the design of the electrocatalyst is the key issue. However, the conventional catalyst suffers from high cost and single activity, thus obtaining high voltage for water splitting and low Faradaic efficiency (FE). Herein, a V-doped Ru/RuP4 Mott–Schottky (M–S) heterojunction is fabricated, and 10%V-Ru/RuP4 has the widest band gap and good sensitivity to the EG oxidative reaction (EGOR), thus showing outstanding electrocatalytic performances with a low EGOR voltage of 1.05 V at 10 mA cm–2 in 1 M KOH + 0.3 M EG. Meanwhile, 10%V-Ru/RuP4 has a good hydrogen evolution reaction (HER) performance with a low HER potential of 119 mV at 10 mA cm–2. Furthermore, the EG is electrocatalytically oxidized to FA via a high FE of 93.9% at 1.5 V. This work provides a special M–S heterojunction for PET degrading and upcycling linked to hydrogen evolution.
