动态氧化还原再生铂位点实现 PET 废弃物长时电合成乙醇酸
Dynamic redox reactivation of platinum sites for long-term glycolate electrosynthesis from polyethylene terephthalate wastes
AI 导读
作者提出动态氧化还原再生策略，在工作电位氧化乙二醇制乙醇酸、在非工作电位通过吸附乙二醇的化学还原复活铂活性位点，在约 220 mA cm⁻² 平均电流密度下稳定运行超过 3000 小时。
推荐理由
PET 解聚产物乙二醇经电氧化制乙醇酸，作者用动态氧化还原再生铂位点把稳定性拉到 3000 小时以上，并给出 10 A 级电解槽的物料与收益数据。
创新点
把失活的铂位点从“一次性消耗”变成可周期性化学还原再生的动态过程，使 PET 衍生乙二醇电氧化制乙醇酸在安培级电流下可重复数十批而不衰减。
