NiMn-MOF as an Efficient Electrocatalyst for Oxygen Evolution Reaction

Among various materials used as electrocatalysts for the oxygen evolution reaction (OER), Metal-organic frameworks (MOFs) have attracted much interest due to their unique properties such as high porosity, tailorable pore size, large specific surface area, simple synthesis, and ample active sites. Here, we report the synthesis, characterization, and OER electrocatalytic performance of a bimetallic metal-organic framework composed of Ni and Mn metals and benzene-۱,۳,۵-tricarboxylic acid linker. NiMn-MOF was prepared via a simple one-step hydrothermal synthesis. It was found that the bimetallic NiMn-MOF exhibits high electrocatalytic activity in OER, with an overpotential of ۳۰۰ mV at the current density of ۳۰ mA cm−۲ and a Tafel slope of ۶۲ mV dec−۱.
