Facile one-pot generation of metal oxide/hydroxide@metal–organic framework composites: highly efficient bifunctional electrocatalysts for overall water splitting

Abstract

In situ growth of Co3O4 nanocubes on the surface of Co-MOF is an effective way to adjust the surface electron structure of electrocatalysts and increase extra active sites for the OER, the HER and overall water splitting. A facile one-pot hydrothermal method can be extended to the preparation of other metal oxide/hydroxide@MOF composites.
