Nitrogen-doped RuS₂ nanoparticles containing in situ reduced Ru as an efficient electrocatalyst for hydrogen evolution.

ABSTRACT: The production of hydrogen via water electrolysis brings hope for the realization of hydrogen economy, but there is still a lack of highly efficient and appropriate electrocatalysts for the generation of hydrogen in practical applications. In particular, reasonable construction and feasible preparation strategies are the essential requirements for excellent electrocatalysts. Herein, the heterostructures of N-RuS₂/Ru nanoparticles were designed by annealing the RuS₂ nanoparticles in ammonia. By introducing a nitrogen dopant and single-phase Ru metal simultaneously, high-efficiency electrocatalytic performance for hydrogen evolution reaction (HER) was implemented, where the electrocatalyst of N-RuS₂/Ru exhibited a low onset overpotential of 76 mV and s
