Hydrogen production for fuel cell via ethanol steam reforming reaction over Ni-Cu/Al_2O_3-SiO_2 catalysts

Ni-Cu-based bimetallic catalysts supported on Al2O3-SiO2 was prepared to study the effect of Cu content on the catalytic performance in the steam reforming reaction of ethanol.Activity tests showed that Ni-Cu-based bimetallic catalyst had the best catalytic performance when Cu content was 5 wt%,with the H2 selectivity for 61.2% at 400 ℃ and 92.0% at 600 ℃.TPR showed much higher Cu content made the interaction between the support and NiO weak.XRD showed when Cu content was 5 wt%,there were high dispersion of Cu oxide in the catalyst,which can improve catalytic performance.
