Nanomaterials (with a particle size less than 10 nm) and with intermediate
physical and chemical properties between molecules-size and a massive-nature
have been of major interest due to their different applications. In this context,
in this work trimetallic nanomaterials (PtxPdyNiz) were prepared varying the
weight ratios of Pt:Pd:Ni (i.e. 48%Pt10%Pd42%Ni, 10%Pt60%Pd30%Ni,
45%Pt30%Pd25%Ni) tris (dibenzylideneacetone) diplatinum Pt2(dba)3, bis
(dibenzylideneacetone) palladium Pd(dba)2 and bis (1,5-ciclooctadiene) nickel
Ni(cod)2 as precursors. All set of catalysts were synthesized in presence of
octylamine (OA, with molar ratio 1:1 metal:stabilizer) and with carbon vulcan as
a support in an organic medium (THF). The obtained materials were evaluated
in the urea oxidation reaction (UOR, as hydrogen-source for fuel-cells
applications) in alkaline medium. The as-synthesized tri-metallic nano-alloys
were characterized by X-ray diffraction (XRD) and transmission electron
microscopy (TEM). The current-versus-potential characteristics obtained cyclic
voltammetry technique showed that i) nickel-amount promotes a major urea
oxidation and ii) the pH of the electrolyte (as observed during experiments as a
function of concentration) has an important effect on the reaction-performance.
