Diamine-capped PtCu nanoparticles have been synthesized by the simultaneous reduction of the corresponding bis-imine metal complexes with hydrogen and supported onto a high-surface-area carbon. The obtained heterogeneous catalyst was tested in thermally conducted aerobic oxidation of ethanol to acetic acid in water as well as in the electrochemical oxidation of ethanol. Both types of catalyses mediated by the PtCu alloy confirmed a notable increase in catalytic activity compared to the pure Pt- and Cu-based counterparts due to a clear bimetallic effect.

Abstract
Diamine-capped PtCu nanoparticles have been synthesized by the simultaneous reduction of the corresponding bis-imine metal complexes with hydrogen and supported onto a high-surface-area carbon. The obtained heterogeneous catalyst was tested in thermally conducted aerobic oxidation of ethanol to acetic acid in water as well as in the electrochemical oxidation of ethanol. Both types of catalyses mediated by the PtCu alloy confirmed a notable increase in catalytic activity compared to the pure Pt- and Cu-based counterparts due to a clear bimetallic effect.File in questo prodotto:
