A self-reactivated PdCu catalyst for aldehyde electro-oxidation with anodic hydrogen production

open access: yesNature Communications
The low-potential aldehyde oxidation reaction can occur at low potential (~0 VRHE) and release H2 at the anode, enabling hydrogen production with less than one-tenth of the energy consumption required for water splitting.
