A hybrid of MIL-53(Fe) rhombus and conductive CoNi₂S₄ nanosheets as a synergistic electrocatalyst for the oxygen evolution reaction

Abstract

Hydrogen energy is considered to be a zero-carbon chemical energy alternative to traditional fossil energy, and electrolysis of water, as one of the most effective methods of producing hydrogen, can...

Electrochemical water splitting enhancement by introducing mesoporous NiCoFe-trimetallic phosphide nanosheets as catalysts for the oxygen evolution reaction

“… 3 Because of the slow four-electron transfer kinetics process of OER, the application of water electrolysis is largely limited, and hence, highly effective electrocatalysts are urgently needed. 4 At present, noble metal materials like IrO 2 and RuO 2 show excellent OER performance under alkaline conditions, but their high cost limits their large-scale application. 5 To achieve highly efficient and economic electrolysis of water, it is critical to develop active, stable and cost-effective electrocatalysts for the OER, which is a thermodynamically unfavorable process.…”
