Electrocatalytic Water Splitting and Hydrogen Production
This community develops catalysts and membrane systems to split water into hydrogen and oxygen using electricity, primarily for the production of clean fuel.
The work centers on designing electrocatalysts for the hydrogen evolution reaction and the oxygen evolution reaction, with a strong emphasis on alkaline media and proton exchange membranes. Recurring materials include nickel foam, layered double hydroxides, and transition metal oxides such as cobalt and nickel compounds. The research focuses on enhancing reaction efficiency, stability, and activity, often through the synthesis of metal-organic frameworks, high-entropy alloys, and atomically dispersed sites. Applications span from laboratory-scale electrolyzers to industrial-scale seawater electrolysis, with specific attention to reducing reliance on precious metals like iridium and platinum.
The largest share of the community's output is found in hydrogen research, accounting for 5.5% of all tracked hydrogen papers, and 23,601 papers here. It also represents 4.8% of oxygen research and 4.4% of nickel research.
The community comprises 47,574 papers, publishing most frequently in the International Journal of Hydrogen Energy, Electrochimica Acta, and Journal of Materials Chemistry A.
Recent work continues to focus on stabilizing catalysts for acidic and alkaline water oxidation, developing durable anion-exchange membrane electrolyzers, and optimizing heterojunctions for enhanced hydrogen evolution kinetics.
