Abstract

Development of low-cost, highly efficient catalysts for water splitting is required to replace precious metal catalysts. CeO x -modified CoP@carbon composites are prepared via Ce-doped metal–organic frameworks. The as-prepared CeO x -modified CoP@carbon composites have excellent electrocatalytic activity with respect to the oxygen evolution reaction, for which an overpotential (η) up to ~ 313 mV is achieved at the current density of 10 mA cm−2. In addition, CeO x -modified CoP@carbon composites show an overpotential of up to 127 mV at the current density of 10 mA cm−2 for the hydrogen evolution reaction, showing excellent catalytic activity for water splitting.
