Ni foam-supported Cu/Cu2O composites for energy-saving hydrogen evolution coupled with ethylene glycol oxidation

Abstract

Electrocatalytic hydrogen production has been considered as the most viable tactic toward green hydrogen future. However, the conventional electrolysis associated with the overall water splitting demands a huge amount of energy, which are induced by extremely high overpotential of anodic oxygen evolution reaction. This investigation attempts to address mentioned obstacles through the development a novel Cu-based electrocatalyst for energy- saving hydrogen production- coupled with the anodic organic compound oxidation reaction
