Abstract:Bimetallic nanoparticles of Au and Ni in the form of alloy nanostructures with varying Ni content are synthesized on reduced graphene oxide (rGO) sheets via a simple solution chemistry route and tested as electrocatalysts towards the hydrogen evolution (HE) and oxygen reduction (OR) reactions using polarization and impedance studies. The Au/>Ni alloy NPs/rGO nanocomposites display excellent electrocatalytic activity which is found to improve with increasing Ni content in the Au<img style=
Keywords:Electrocatalysis  Au– Ni alloy nanoparticles  Reduced graphene oxide  Hydrogen evolution reaction  Oxygen reduction reaction  High stability
