Abstract
Oxidation of ethanol was studied at Snad modified and unmodified Pt3Sn/C and Pt/C catalysts. Pt3Sn/C and Pt/C catalysts were characterized by XRD. Potentiodynamic and chronoamperometric measurements were used to establish catalytic activity and stability. High activity achieved at Snad modified Pt3Sn/C catalyst has not been observed at any bimetallic catalyst so far. Promotional effect of Snad on the ethanol oxidation was related to the enhancement of CO oxidation rate in bifunctional mechanism. It was shown that electrodeposited Sn exhibited different effect on the catalytic activity compared to Sn in alloy.
