Noble metal nanoparticles impregnated into zeolites for ethanol oxidation reaction in alkaline medium

Nowadays, the direct ethanol fuel cell (DEFC) with the electro- oxidation of ethanol as its anode reaction is becoming a promising green power source for portable device applications owing to its advantages of higher open circuit voltage, high current density, safer fuel and easy to handle compared to Hydrogen. In spite of the research effort to find out a cheap anode with high performance for fuel cell application, expensive noble metals are still in use. For this reason, more effort must be devoted to reduce the amount of noble metal loading while the high reactivity is still retained. In order to fulfill this demand, high dispersion of noble metal-containing catalyst on different cheap and conducting substrates has been extensively studied. In this work, noble metal nanoparticles dispersed in zeolites layer have been prepare d, by loading the Zeolites layer onto graphite substrate using drop casting technique, followed by impregnation ino metal salt solution, and then tested for ethanol oxidation in alkaline solution using cyclic voltammetry
