Herein, Fe-incorporated Co₃(PO₄)₂·8H₂O (FCPO) was successfully synthesized via a simple hydrothermal method. Notably, compared with Co-based phosphate electrocatalysts, the Fe incorporation modulates the electronic structure surrounding cobalt centers, facilitates cobalt valence transitions during OER. Besides, the exact location of Fe incorporation is determined through x-ray absorption and clarified the role of Fe in cobalt phosphate catalyst for OER.

This study establishes plasma-driven biocatalysis using a nanosecond pulsed microwave plasma torch (npMWPT), highlighting its unique advantages over previously applied sources. npMWPT-driven biocatalysis addresses insufficient plasma-generated H₂O₂ production by enabling continuous H₂O₂ supply while decoupling plasma treatment from enzymatic reactions. We investigated the effectiveness of npMWPT-driven biocatalysis using both immobilized and free recombinant unspecific peroxygenase from <i>Agrocybe aegerita</i> (r<i>Aae</i>UPO) to convert ABTS and ethylbenzene. For ABTS, immobilized r<i>Aae</i>UPO demonstrated reusability across five reaction cycles (turnover number TON 44,637 µmol_ABTS* µmoL⁻¹_r<i>_Aae</i>_UPO). The decoupling of npMWPT-based H₂O₂ production resulted in a TON of 66,495 µmol₍<i>_R</i>_)-1-PhOl µmoL⁻¹_r<i>_Aae</i>_UPO with ethylbenzene for free r<i>Aae</i>UPO, outperforming the use of immobilized r<i>Aae</i>UPO for the first time in plasma-driven biocatalysis (TTN 22,116). Mixing optimization improved conversion rates, while observed enzyme inactivation under continuous operation revealed that H₂O₂ generation exceeded enzymatic consumption under the investigated conditions. The present study identifies supply-demand matching as the key optimization target for npMWPT-driven biocatalysis. This proof-of-principle work demonstrates the successful integration of spatially decoupled npMWPT H₂O₂ generation with peroxygenase-based biocatalysis and provides a basis for future process-controlled plasma-driven biocatalysis.</p>","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"18 17","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cctc.71023","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148856729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its industrial implementation is severely hindered by its highly endothermic nature and the rapid catalyst deactivation originating from metal sintering and carbon deposition. This review provides a comprehensive analysis of DRM technology, linking fundamental surface steps to advanced catalyst design strategies. It begins by clarifying the inherent thermodynamic and kinetic constraints, detailing the reactant activation, and uncovering the essence of catalyst deactivation. The design strategies for synthesizing durable and cost-effective DRM catalysts are categorized into two dimensions: active site engineering (e.g., particle downsizing, bimetallic alloying, and promoter incorporation) and functional support modulation (e.g., acidity–basicity adjustment, oxygen vacancy generation, and multi-functional confinement). Finally, this review proposes a multi-dimensional roadmap for future commercialization. We emphasize the integration of data-driven machine learning (ML), energy-assisted catalysis, macroscopic process intensification, and techno-economic analyses.
