Corrosion Engineering of Part-Per-Million Single Atom Pt/Ni(OH) Electrocatalyst for PET Upcycling at Ampere-Level Current Density.

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 plastic down-cycling, the electrochemical strategy of recovering valuable monomers enables an ideal, circular plastic economy. Here a corrosion synthesized single atom Pt/Ni(OH) electrocatalyst with part-per-million noble Pt loading for highly efficient and selective upcycling of polyethylene terephthalate (PET) into valuable chemicals (potassium diformate and terephthalic acid) and green hydrogen is reported.

High-Surface Area Mesoporous ScO with Abundant Oxygen Vacancies as New and Advanced Electrocatalyst for Electrochemical Biomass Valorization.

Scandium oxide (ScO) is considered as omnipotent "Industrial Ajinomoto" and holds promise in catalytic applications. However, rarely little attention is paid to its electrochemistry. Here, the first nanocasting design of high-surface area ScO with abundant oxygen vacancies (mesoporous V-ScO) for efficient electrochemical biomass valorization is reported.
