  • Ru nanoparticles supported on titanium oxynitride as efficient catalysts for alkaline hydrogen evolution reaction : European patent application EP 4 603 181 A1, 2025-08-20
    Smiljanić, Milutin ; Hodnik, Nejc, dipl. kemik ; Bele, Marjan
    The invention provides a novel and efficient catalyst for HER composed of Ru nanoparticles dispersed over a support consisting of titanium oxynitride and high surface area carbon material, such as ... graphene oxide, (TiON-C) with a particularly low Ru loading of only 6 wt.%. In an alkaline electrolyte, the Ru/TiON-C composite significantly surpasses the HER performance of the Ru/C analog. More importantly, Ru/TiON-C is both intrinsically (nearly 3 times higher turnover frequency) and practically (4 times higher mass activity) better performing HER catalyst than the commercial Pt/C benchmark.
