In Situ Construction of Cu1+/Cu0 and Cu2+/Cu0 Pairs of Cu‐Based Catalysts for Electrocatalytic Nitrate Reduction

Advanced Science, EarlyView.
CuO and CuPO (Cu2P2O7 and Cu3(PO4)2) as precursors are in suit construction two distinct copper‐based active sites during the NO3RR reaction: Cu1+/Cu0 (derived from CuO) and Cu2+/Cu0 (derived from CuPO). Cu1+/Cu0 is the key to achieving high activity and high selectivity.

*OH Adsorption‐Mediated Electrochemical Oxidation of 5‐Hydroxymethylfurfural to Selective 2,5‐Furandicarboxylic Acid at pH 12

Advanced Science, EarlyView.
Under the weakly alkaline condition, at pH 12, the *OH adsorption–mediated mechanism of direct aldehyde oxidation is demonstrated to complete HMF oxidation to FDCA, obtaining >95% selectivity and yield. In OH−‐deficient media, high FDCA selectivity is achieved on the CuO/NiOOH interface, a synergistic active site, where Cu enhances *OH utilization, and

Chemical Upcycling of Polyphenylene Sulfide at Room Temperature

Advanced Science, EarlyView.
Poly(phenylene sulfide) (PPS) is a semi‐crystalline super engineering plastic with exceptional properties. An iron‐photocatalyzed strategy is reported for chemical upcycling of PPS plastics at room temperature using 1,2‐dichloroethane. The method demonstrates remarkable efficiency across diverse PPS resins and post‐consumer composites, even within ...
