Nitrogen-doped graphene quantum dots as a support for Ni-Au nanoparticles: efficient electrocatalysts for ethanol and formate fuel cells using hydrogen peroxide as oxidant

The obtained results from half-cell and single fuel cell configurations confirm the superiority of the Ni 1 Au 1 -NGQD electrocatalyst towards the oxidation of both fuels (ethanol and formate) compared to the two other electrocatalysts.
