Abstract Electro‐reforming of poly(ethylene terephthalate) (PET) into valuable chemicals is garnering significant attention as it opens a mild avenue for waste resource utilization.

Abstract The plastic waste issue has posed a series of formidable challenges for the ecological environment and human health. While conventional recycling strategies often lead to down‐cycling, electrochemical strategy recovering valuable monomers enables an ideal, circular economy. Here corrosion synthesized single atom Pt 1 /Ni(OH) 2 electrocatalyst with part‐per‐million noble loading highly efficient selective upcycling polyethylene terephthalate (PET) into chemicals (potassium diformate terephthalic acid) green hydrogen is reported. Electro‐oxidation PET hydrolysate, ethylene glycol (EG), formate processed high Faraday efficiency (FE) selectivity (>90%) at current density close 1000 mA cm −2 (1.444 V vs RHE). in situ spectroscopy functional theory calculations provide insights mechanism understanding efficiency. Remarkably, electro‐oxidation EG ampere‐level also successfully illustrated by using membrane‐electrode assembly FEs integrated production 500 h continuous operation. This process allows chemical space‐time yield profitable (588–700 $ ton −1 PET), showing industrial perspective on single‐atom catalysis upcycling.

Abstract The electrochemical oxygen reduction reaction (ORR) to produce hydrogen peroxide (H 2 O ) is appealing due its sustainability. However, efficiency compromised by the competing 4e − ORR pathway. In this work, we report a hierarchical carbon nanosheet array electrode with single-atom Ni catalyst synthesized using organic molecule-intercalated layered double hydroxides as precursors. exhibits excellent 2e performance under alkaline conditions and achieves H yield rates of 0.73 mol g cat −1 h in H-cell 5.48 flow cell, outperforming most reported catalysts. experimental results show that atoms selectively adsorb , while nanosheets generate reactive species, synergistically enhancing production. Furthermore, coupling system integrating ethylene glycol oxidation significantly enhances rate 7.30 producing valuable glycolic acid. Moreover, convert electrolyte containing directly into downstream product sodium perborate reduce separation cost further. Techno-economic analysis validates economic viability system.
