Dual Doping in Precious Metal Oxides: Accelerating Acidic Oxygen Evolution Reaction

International Journal of Molecular Sciences, Год журнала: 2025, Номер 26(4), С. 1582 - 1582

Опубликована: Фев. 13, 2025

Developing a highly active and stable catalyst for acidic oxygen evolution reactions (OERs), the key half-reaction proton exchange membrane water electrolysis, has been one of most cutting-edge topics in electrocatalysis. A dual-doping strategy optimizes electronic environment, modifies coordination generates vacancies, introduces strain effects through synergistic effect two elements to achieve high catalytic performance. In this review, we summarize progress dual doping RuO2 or IrO2 OERs. The three main mechanisms OERs are dicussed firstly, followed by detailed examination development history catalysts, from experimentally driven systems machine learning (ML) theoretical screening systems. Lastly, provide summary remaining challenges future prospects, offering valuable insights into

Advancing the Understanding of Oxygen Vacancies in Ceria: Insights into Their Formation, Behavior, and Catalytic Roles

JACS Au, Год журнала: 2025, Номер unknown

Опубликована: Март 28, 2025

Oxygen vacancies (OV's) in ceria (CeO2) are critical structural and electronic features that underpin ceria's remarkable oxygen storage capacity, redox catalytic performance, wide-ranging applications catalysis, solid oxide fuel cells, gas sensors. These vacancies, which result from the removal of atoms, enable dynamic exchange between its environment, profoundly influencing properties. The intricate surface structures play a key role determining properties interactions with supported metal catalysts. Over past decade, advancements state-of-the-art situ characterizations, first-principles calculations, emerging machine learning frameworks have significantly enhanced our understanding formation mechanisms, behaviors, roles OV's. This perspective highlights recent experimental theoretical progress research, emphasizing interplay reactive environments. Additionally, addresses challenges elucidating defect chemistry explores opportunities to tailor using multiscale modeling AI-driven methodologies.

Plasmonic Supramolecular Nanozyme‐Based Bio‐Cockleburs for Synergistic Therapy of Infected Diabetic Wounds

Advanced Materials, Год журнала: 2024, Номер unknown

Опубликована: Окт. 23, 2024

Abstract Diabetic wounds are a major devastating complication of diabetes due to hyperglycemia, bacterial invasion, and persistent inflammation, the current antibiotic treatments can lead emergence multidrug‐resistant bacteria. Herein, bimetallic nanozyme‐based biomimetic bio‐cocklebur (GNR@CeO 2 @GNPs) is designed synthesized for diabetic wound management by depositing spiky ceria (CeO ) shells gold nanoparticles (GNPs) on nanorod (GNR) nanoantenna. The plasmonic‐enhanced nanozyme catalysis self‐cascade reaction properties simultaneously boost two‐step enzyme‐mimicking catalytic activity GNR@CeO @GNPs, leading significant improvement in overall therapeutic efficacy rather than mere additive effects. Under glucose activation 808 nm laser irradiation, @GNPs material captures photons promotes transfer hot electrons from GNR GNPs into CeO , realizing “butterfly effect” consuming local glucose, overcoming limited antibacterial efficiency an individual PTT modality, providing substantial reactive oxygen species. In vitro vivo experiments demonstrate material's exceptional antibiofilm against Gram‐negative Gram‐positive bacteria, which reduce promote collagen deposition, facilitate angiogenesis, thereby accelerating healing. This study provides promising new strategy develop nanozymes with cascade mode antibiotic‐free synergistic treatment infected wounds.
