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 ...

Surface‐Bound Superoxide Radical‐Mediated Photo‐Fenton Mineralization of Ciprofloxacin on Fe‐Sillenite Nanosheets

Advanced Science, EarlyView.
This study systematically compares the degradation efficiency of CIP in a H2O2‐alone system and a novel Bi12FeO20‐H2O2 photo‐Fenton system. It reveals for the first time the presence of a quinone‐imine intermediate in the H2O2‐alone system, which exhibits toxicity comparable to CIP.

A Polymer‐Intercalated Modulation Assembly Strategy Towards Mesoporous Single‐Crystalline BiVO4 Materials for Enhanced Photocatalytic Performance

Advanced Science, EarlyView.
A polymer‐intercalated modulation assembly strategy was proposed to synthesize mesoporous single‐crystalline BiVO4 with tunable pore structure by co‐assembly of inorganic–organic composite through coordination bonds and hydrogen bonds. Thanks to single‐crystalline properties and mesoporous structure with vanadium vacancy microenvironment, the prepared ...
