Abstract

Development of high-performance, durable and cost-effective Pt-based catalysts is essential for improving oxygen evolution reaction (OER) under alkaline conditions. In this study, we introduce a dual-phase PtNiCuMnMo high-entropy alloy (HEA) catalyst with an OER overpotential of 250 mV and a Tafel slope of 124 mV/dec at a current density of 10 mA/cm². Remarkably, the PtNiCuMnMo HEA catalyst maintains 77 % of its activity after 64 h at a current density of 200 mA/cm². Theoretical calculations further validate the remarkable OER performance of the PtNiCuMnMo HEA catalyst, highlighting its favourable adsorption and charge transfer characteristics. The exceptional OER activity of the PtNiCuMnMo HEA catalyst considerably surpass those of commercial RuO₂ catalysts, highlighting the potential of this catalyst to revolutionise water-splitting technology.
