Abstract | Cited by

Monodisperse platinum nanoparticles (Pt NPs) furnished with a Vulcan Carbon-Activated Carbon (VC-AC) hybrid have been prepared in the presence of tripropylamine (TPrA) and used as novel catalysts (Pt NPs/TPrA@VC-AC) for formic acid oxidation (FAO) reactions at room temperature. The characteristics of the novel catalysts have been characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), high resolution transmission electron microscopy (HRTEM), cyclic voltammetry (CV) and chronoamperometry (CA). The X-ray diffractograms of all the prepared electrocatalysts showed the typical face-centered cubic (FCC) structure. Chronoamperometry and cyclic voltammetry measurements showed a strong increase in the performance of Pt NPs/TPrA@VC, Pt NPs/TPrA@AC and Pt NPs/TPrA@VC-AC hybrid material electrocatalysts after formic acid addition, but the Pt NPs@VC-AC electrocatalyst showed the best performance compared to Pt NPs/TPrA@VC and Pt NPs/TPrA@AC.
