Chemical Vapor Deposition of Ru/RuSe2 Catalyst for Electrolytic Hydrogen Evolution Reaction

Abstract A one‐step synthesis of highly stable Ru/RuSe 2 nanoparticles (NPs) on carbon paper is achieved using low temperature and pressure chemical vapor deposition (CVD), resulting in a heterointerface with multiple active sites for catalysis. The catalyst exhibits outstanding performance for the hydrogen evolution reaction (HER) in an alkaline solution, with low overpotentials and fast hydrogen adsorption and desorption kinetics. The Ru/RuSe 2 /C nanoparticle structure has the potential for large‐scale production and can be used as an efficient catalyst for HER.
