Summary
Hydrogen is a vital chemical feedstock for the chemical industry. It is essential in applications ranging from fuel production to manufacturing plastics and fine chemicals. Hydrogen can be produced by water electrolysis, which uses electricity to split water into hydrogen and oxygen. However, today’s water-splitting technologies use expensive and scarce metals. They gradually degrade under harsh operating conditions, which reduces performance, increases costs, and slows the adoption of water electrolysis. The reasons why the metals degrade are unclear, which makes it difficult to design altern
