Alloying and interface effects endow supported PtRuCo nanochains with 70 000-cycle stability in hydrogen evolution under neutral conditions

A series of ultrasmall-PtRuCo-cluster-assembled nanochains supported on hollow N-doped Mo<sub>2</sub>C "nanoflower" catalysts was successfully synthesized. Owing to the alloying and interface effects, the optimized Pt<sub>0.5</sub>Ru<sub>0.22</sub>Co<sub>0.28</sub>/Mo<sub>2</sub>C achieves an ultralow overpotential (24 mV@10 mA cm<sup>-2</sup>) and ultralong cycling life (70 000 cycles) in neutral media.

Abstract

A series of ultrasmall-PtRuCo-cluster-assembled nanochains supported on hollow N-doped Mo<sub>2</sub>C "nanoflower" catalysts was successfully synthesized. Owing to the alloying and interface effects, the optimized Pt<sub>0.5</sub>Ru<sub>0.22</sub>Co<sub>0.28</sub>/Mo<sub>2</sub>C achieves an ultralow overpotential (24 mV@10 mA cm<sup>-2</sup>) and ultralong cycling life (70 000 cycles) in neutral media.
