Developing highly efficient, cost-effective, non-noble-metal-based electrocatalysts with superior performance and stability for oxygen evolution reactions is of immense challenge as well great importance the upcoming sustainable green energy conversion technologies. The multivariate metal-organic frameworks hierarchical porous structures unsaturated coordination modes are considered to be promising emerging materials. In this work, a series multimetallic MOFs were directly grown on nickel foam (NF) through solvothermal method. Notably, optimized tetrametallic FeCoNiMn-MOF/NF shows low overpotential 239 mV achieve current density 50 mA cm
