The exploitation of high catalytic activity electrocatalysts with abundant earth reserves is the prerequisite for extensive hydrogen production from water electrolysis. Herein, based on a feasible design idea, we fabricate an iron and oxygen co-doped nickel phosphide ((Fe0.1Ni0.9)(2)P(O)) by phosphating metal-organic framework (MOF) derivatives supported on nickel foam (NF) for efficient water splitting. In 1.0 M KOH, the (Fe0.1Ni0.9)(2)P(O)/NF electrode only requires an overpotential of 240 mV to reach 100 mA cm(-2) for the OER and 87 mV to reach 10 mA cm(-2) for the HER, respectively. Encouragingly, an alkaline electrolyzer assembled with the (Fe0.1Ni0.9)(2)P(O)/NF electrode can achieve a current density of 10 mA cm(-2) at an extremely low voltage of 1.50 V, which is one of the lowest values currently achievable with non-precious metal electrocatalysts. Undoubtedly, this work provides a novel and practical strategy to synthesize highly efficient and durable electrocatalysts based on MOF derivatives for overall water splitting and other electrocatalysis.
