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 a…
