Ultrathin Trimetallic Metal-Organic Frameworks Nanosheets for Highly Efficient Oxygen Evolution Reaction

Abstract

Metal organic frameworks (MOFs) are seldom used as the catalyst in oxygen evolution reaction due to the lower conductivity, fewer activity center and ion transfer passage. In this study, a bimetallic/trimetallic ZIF nanosheets was successfully synthesized by using 2-methylimidazole as an organic ligand. The 2D structure provided the more active center and ion transfer passage, the trimetallic structure increased the conductivity, which lead to this ZIF nanosheets exhibits a more active property with an overpotential of 216 mV at 100 mA cm-2 with Tafel slope of 23.25 mV dec-1 in 1 M KOH, and has good stability under alkaline conditions.
