Electrocatalysts for Water Splitting and Hydrogen Production
This community develops catalysts and membrane systems to split water into hydrogen and oxygen, a process used to produce green hydrogen fuel.
The work centers on designing materials for the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), often combined in overall water splitting. Recurring materials include nickel foam, layered double hydroxides, metal-organic frameworks, and oxides of cobalt, nickel, and transition metals. The research focuses on enhancing efficiency and stability in both alkaline and acidic environments, with specific attention to proton exchange membranes and anion exchange membranes. Applications range from laboratory-scale electrolysis to industrial-scale hydrogen generation, including the use of seawater as a feedstock.
The community represents 19.6% of all tracked oxygen research and 15.1% of hydrogen research. It also accounts for 10.5% of iridium research and 9.5% of cobalt research.
There are 30,363 papers in this community, published primarily in the International Journal of Hydrogen Energy, Journal of Materials Chemistry A, and Chemical Engineering Journal.
Recent work continues to focus on stabilizing lattice oxygen in acidic conditions, engineering interfacial water structures, and developing non-precious metal catalysts for durable hydrogen production.
