The feasibility of obtaining ruthenium oxide nanoparticles on a carbon support by pyrolysis of polymeric ruthenium complexes is shown. The performance efficiency of such a catalyst considerably surpasses the efficiency of catalysts synthesized using monomer ruthenium compounds and is comparable with figure of merit values reported for the best samples of hydrogen evolution reaction catalysts in alkaline media, while the specific consumption of the precious metal in this catalyst is much lower.
