A highly active hydrazine fuel cell catalyst consisting of a Ni-Fe nanoparticle alloy plated on carbon materials by pulse reversal

A noble metal-free, highly active electrocatalyst for hydrazine fuel cells has been prepared by pulse reversal plating. Plating Ni-Fe alloy on carbon materials (multi-walled carbon nanotubes and graphene) to produce electrocatalysts is facile, rapid, proceeds at low temperature, and does not damage the sp(2) hybridization of the carbon support.
