Developing efficient and durable electrocatalysts for the oxygen evolution reaction (OER) in proton exchange membrane (PEM) electrolyzers represents a significant challenge. Herein, the cobalt‐ruthenium oxide nano‐heterostructures are successfully synthesized on carbon cloth (CoOx/RuOx‐CC) for acidic OER through a simple and fast solution combustion strategy. The rapid oxidation process endows CoO...
Perovskite oxides are studied as electrocatalysts for oxygen evolution reactions (OER) because of their low cost, tunable structure, high stability, and good catalytic activity. However, there are two main challenges for most perovskite oxides to be efficient in OER, namely less active sites and low electrical conductivity, leading to limited catalytic performance. To overcome these intrinsic obstacles,...
Perovskite Oxide‐Based Electrocatalysts
In article number 2101605, Shi Chen, Shuangpeng Wang, Guichuan Xing, Hui Pan, and co‐workers systematically summarize perovskite oxides as electrocatalysts for efficient oxygen evolution reaction (OER). The catalytic mechanism and descriptors for perovskite oxides are also discussed in detail. Additionally, various strategies to improve the OER catalytic performance...
In article number 1907029, Jianying Huang, Jun Hu, Yuekun Lai, Yuxin Tang, and co‐workers reveal a correlation between the oxygen evolution reaction overpotential and the cobalt‐based electrode composition in an electrospinning “Microparticles‐in‐Spider Web” superstructure electrode, leading to remarkable electrocatalytic activity.
Sluggish kinetics of the multielectron transfer process is still a bottleneck for efficient oxygen evolution reaction (OER) activity, and the reduction of reaction overpotential is crucial to boost reaction kinetics. Herein, a correlation between the OER overpotential and the cobalt‐based electrode composition in a “Microparticles‐in‐Spider Web” (MSW) superstructure electrode is revealed. The overpotential...
