Trimetallic-organic framework/MXene composite as an oxygen evolution reaction electrocatalyst with elevated intrinsic activity

A composite of trimetallic Fe 2.1 Ni 0.2 Co 0.7 -MIL-88A grown on Ti 3 C 2 T x MXene nanosheets was successfully synthesized and employed as a high-performance OER electrocatalyst with a low overpotential of 231 mV at 10 mA cm −2 current density in alkaline media.
