Amorphous versus nanocrystalline RuO₂ electrocatalysts: activity and stability for oxygen evolution reaction in sulfuric acid

Abstract

Ruthenium oxide (RuO2) electrocatalysts possessing high activity and stability are needed to sustain the oxygen evolution reaction (OER) under harsh anodic conditions in acidic water electrolysis systems. Herein, we report...

Tailoring the Active Sites of Nanosheet NiSe/NiSe2 Catalyst by Pulse Electrodeposition on the 3D Microporous Ni-Cu/NF Substrate for both Hydrogen and Oxygen Evolution Reactions

“…Therefore, alternative energy forms are being generated by converting various sources of energy. 1,2 Hydrogen gas has always been perceived as an excellent energy carrier due to its clean and renewable nature, high energy density, and superior energy conversion efficiency, especially in fuel cells. [3][4][5][6] The major routes for acquiring hydrogen energy are the reformation of fossil energy, electrocatalytic water splitting, and photocatalytic decomposition of water.…”
