Ammonia splitting with electrode alternating for durable hydrogen production (opens in new tab)

Ammonia is a promising hydrogen carrier. However, its practical deployment hinges on cost-effective splitting approaches to release hydrogen. Ammonia electrolysis, combining the ammonia oxidation reaction (AOR) and the hydrogen evolution reaction, is a promising decentralized solution that operates under mild conditions. Nevertheless, the susceptibility of nearly all AOR catalysts to severe poisoning compromises activity and stability. Here we show an electrode-alternating approach to regener...
