摘要：

Reduced graphene oxide supported nickel tungstate (rGO/NiWO4) nanocomposites (NCs) were synthesized by molten salts followed by hydrothermal treatment at 120 degrees C. XRD, Raman, FTIR and electron microscopic studies reveal the formation of rGO/NiWO4-NCs. The prepared rGO/NiWO4-NCs exhibit enhanced hydrogen evolution reactions (HER) than pure NiWO4 nanoparticles. The nanocomposites as the electro-catalysts deliver low onset potential (-1.35 V), low Tafel value (250 mV/dec), high current density (similar to 40 mA/cm(2)) and good stability for HER in alkaline medium compared to pure NiWO4.
