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

open access: yesAdvanced 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

open access: yesAdvanced 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 ...

Ce‐Doped Lignin‐Based Nanozyme with Heat‐Activated Hydrolase Activity

open access: yesAdvanced Science, EarlyView.
A novel Ce‐doped lignin‐based hydrolase nanozyme (Ce‐AL) is synthesized using Ce ions coordinated with aminated industrial lignin. The Ce‐AL effectively hydrolyzes phosphate ester bonds and protein amide bonds, maintain high activity at 100°C, and successfully fights bacteria biofilms.
