Abstract

Efficient and stable electrocatalysts for hydrogen evolution reaction (HER) are essential to build a new energy system based on clean energy by using electrolytic water for hydrogen production. As commercial Pt/C is limited in its application due to its cost and durability, the exploitation of high-performance, stable catalysts with high Pt utilization is crucial for the development of electrolytic water for hydrogen production industry. Herein, we report a simple and reliable grinding-heating strategy to successfully construct the multi-metallic component nanosheets (PtRuMn), which exhibit excellent activity and good stability under both acidic and basic environments. The as-prepared PtRuMn showed excellent HER performance with a low overpotential of 41 mV (1 M KOH) or 36 mV (0.5 M H2SO4) to reach the current density of 100 mA cm-2 and maintained approximately 95% of the initial current density after a 12 h chronoamperometry (CA) test. This work provides an effective method to improve the utilization of precious metals and to design and develop high-performance HER catalysts, which are important for the application of multiple types of electrolytic water devices at scale.
