Relationship among the physicochemical properties, electrocatalytic performance and kinetics of carbon supported Pt catalyst for ethanol oxidation

---

Abstract.
A new carbon supported Pt (Pt/C(b)) catalyst was prepared by reducing H2PtCl6 in glycol solution using
formic acid as a reducing agent, and has been found in this work to be highly active and stable for the
electrochemical oxidation of ethanol. The preparation produces highly dispersed Pt particles, of 2.6 nm
average size, and with high electrochemical surface area, 98 m2/g. The apparent activation energy of
ethanol oxidation over the Pt/C(b) catalyst electrode is low, 10–14 kJ/mol, over the range of potentials
from 0.3 to 0.6 V.

Keywords: Carbon supported platinum catalyst, Ethanol oxidation, Electrocatalytic activity and stability
