    Metallic transition metal dichalcogenides are promising catalysts for hydrogen evolution reactions but their performances are still lower than industrial Pt and Ir electrolysers. The metallic 2H phase of niobium disulfide now exhibits enhanced current densities versus a reversible hydrogen electrode.
