Two methods were developed to coat activated carbon with NiPt(CN)4 nanosheets by reacting potassium tetracyanoplatinate(II) with nickel(II) sulfate in the presence of the carbon substrate. The modification of pH released nickel(II) ions from the carbon surface to participate in the reaction. Upon pyrolysis, a Pt-Ni alloy was formed. Based on EDS and XPS data, platinum had segregated to the surface of the metallic structure in higher concentration samples. The Pt-Ni catalyst exhibited significant activity in the hydrogenation of styrene to ethylbenzene. When compared to a catalyst prepared by traditional methods, the Pt-Ni catalyst prepared from NiPt(CN)4 nanosheet precursors exhibited up to 2.8x the activity on a platinum metal basis.
