Spin configuration modulation of Co₃O₄ by Ru doping for boosting the overall water splitting and hydrazine oxidation reactions

Abstract

Co-based spinel oxides with unique crystal structures have been identified as a class of promising candidates for alkaline water oxidation catalysis in oxide structural families. Unfortunately, the relatively poor conductivity...

Constructing a medium-entropy spinel oxide FeNiMnO4/CeO2 heterojunction as a high-performance electrocatalyst for the oxygen evolution reaction

“…9–13 However, the slow kinetics and high overpotential greatly confine the OER, leading to considerable loss of energy during the reaction. 14–17 Currently, iridium (Ir) and ruthenium (Ru) based materials serve as efficient commercial electrocatalysts to accelerate the OER, yet the scarcity of noble metals limits their widespread application. 18–20 Therefore, it is imperative to develop non-noble metal based electrocatalysts, which are not only suitable for large-scale application but also exhibit exceptional performance.…”
