Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Март 20, 2025

Abstract Energy electrocatalytic reactions such as hydrogen evolution reaction, oxygen reduction nitrogen carbon etc., are important to solve the current energy shortage and increasing environmental problems. Developing novel efficient catalyts for these has become an essential urgent issue. Catalysts incorporating bridge‐oxygen bond have received attention due their superior conductivity stability, which favorable optimizing reaction mechanism improving kinetics. This paper provides a comprehensive review encompassing concept of bond, means characterization, activity in electrocatalysis effect on catalytic performance. Through this review, it is expected furnish valuable reference rational design catalysts featuring structure across diverse reactions.

Elevating the selectivity of two-electron oxygen reduction reaction (2e‒ ORR) is challenging. Herein, hydroxyl combined with nitrogen on biomass carbon exhibits a high H2O2 over wide potential range 0 V to 0.5 vs. RHE, which nearly 97% at 0.3 RHE. The combination and improves adsorption desorption intermediates, finally changing pathway promoting 2e‒ ORR. Faradaic efficiency (FE) reaches 98% Furthermore, typical organic pollutants were degraded site in flow cell. This work illustrates

Electron Shuttling of Iron‐Oxygen‐Cobalt Bridging in Cobalt Assembled Iron Oxyhydroxide Catalyst Boosts the Urea Oxidation Stability and Activity

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Март 21, 2025

Abstract Iron (Fe)‐based materials hold great potential as urea oxidation reaction (UOR) catalysts, however, the deactivation of active Fe‐oxyhydroxide (FeOOH) species induced by its dissolution during catalytic process under high current densities is still significant challenge. Herein, cobalt (Co) assembled FeOOH constructed, and formation Iron‐Oxygen‐Cobalt (Fe‐O‐Co) bridging triggers electron transfer from Co to Fe sites. This shuttling induces low valence state sites in FeOOH. Co‐FeOOH catalyst achieves a density 1000 mA cm −2 at voltage merely 1.59 V, showing substantial improvement compared pure (1.97 V). Meanwhile, urea‐assisted anion exchange membrane electrolyzer, after 24 h continuous operation , fluctuation 12.4%, significantly lower than that (49.9%). The situ experiments theoretical calculations demonstrate Fe‐O‐Co endows suppressive Fe‐segregation, fast charge Fe(Co)OOH phase negative‐shifted d‐band center metal sites, boosting UOR stability activity.
