Abstract: Ru doped amorphous hollow copper hydroxide nanowires on copper foam (Ru-Cu(OH) x /CF) is prepared by surface chemical oxidization and following solvothermal process. The hollow 3D nanowires structure provided abundant accessibility active sites, enhanced the electrocatalytic HER performance. [Display omitted] • The as-synthesized Ru-Cu(OH) x /CF electrocatalyst exhibits impressive electrocatalytic performances for HER in full pH range. • The hollow 3D nanowires structure provided abundant accessibility active sites, enhanced the electrocatalytic HER performance. • The overall water-splitting can be powered by sustainable energies, including solar, wind and thermal energies. Developing efficient and stable catalysts for electrocatalytic hydrogen evolution reaction (HER) with low overpotential is the key point to realizing large-scale hydrogen commercialization. Herein, Ru doped amorphous hollow copper hydroxide nanowires on copper foam (Ru-Cu(OH) x /CF) is prepared by surface chemical oxidization and following solvothermal process. The hollow 3D nanowire structure can provide abundant accessibility active sites, promote electrolyte in filtration and facilitate gas diffusion in the process of the electrochemical reaction. Then, the as-synthesized Ru-Cu(OH) x /CF electrocatalyst exhibits impressive electrocatalytic performance for HER with 45, 80 and 50 mV to drive 10 mA cm−2 in 1.0 M KOH, 1.0 M phosphate-buffered saline (PBS) and 0.5 M H 2 SO 4 , respectively, with remarkable long-term stability. Moreover, sustainable energies can power the two-electrode setup with amounts of hydrogen generation. The strategy may be particularly beneficial to explore simple synthesis and high-performance catalysts for HER. [ABSTRACT FROM AUTHOR]
