Cobalt layered double hydroxides derived CoP/Co₂P hybrids for electrocatalytic overall water splitting

Abstract

Cobalt layered double hydroxides (Co-LDHs) obtained by an imidazole-assisted route were used as precursors to prepare dual-functional electrocatalysts CoP/Co₂P. CoP/Co₂P showed an enhanced electrocatalytic performance for HER and OER. The reason was attributed to porous sheets providing more catalytic sites and multi-components improving conductivity and substrate adsorption capability.
