A Cu3P@NiFe-MOF Hybrid as an Efficient Electrocatalyst for Hydrogen and Oxygen Evolution Reactions

For hydrogen and oxygen evolution reactions, the price of precious metals and their long-time testing stability limit their range of use and increase the difficulty of commercialization. Thus, it is necessary to use non-noble metal materials with excellent activity and stability to replace noble metal materials as electrocatalysts. Herein, an efficient and durable electrocatalyst consisting of Cu3P@NiFe-MOF is synthesized by hydrothermal method. Specially, the as-prepared Cu3P@NiFe-MOF-4 delivery an overpotential of 226 mV at a current density of 10 mA cm−2, and it also has a very low Tafel slope and a high double layer capacitance.
