摘要：The amorphous ternary MnCoB was synthesized at room temperature, which showed excellent oxygen evolution reaction (OER) activity and long-term stability in 1.0 mol L-1 KOH solution. The obtained catalyst exhibited the lower overpotential (292 mV) and the Tafel slope was 92.4 mV dec(-1) when the current density arrived 10 mA cm(2). Density functional theory (DFT) calculations elucidated its electrocatalytic activity and the favorable OER kinetics on MnCoB catalyst. Combined theoretical study with experimental observations, this work explained the OER activity mechanism of the catalyst, which was of important guiding significance for design, synthesis and performance of high efficiency electrocatalyst.
