Rapid co-reduction synthesis of ultrafine multi-principal element alloy nanocatalysts for efficient hydrogen evolution

Abstract

A rapid co-reduction strategy for the synthesis of ultrafine and composition-tunable multi-principal element alloy catalysts is proposed. This method necessitates only a 10-minute reaction time at 180 °C and features straightforward setups. The as-synthesized carbon-supported RuPtIrSnCu nanoparticles exhibit superior hydrogen evolution reaction performance in acidic media due to synergistic effects among their multiple components.
