摘要

Catalytic systems for the oxidative methanol reforming (OSMR) with a 1%and 2%metal loading were prepared impregnating the spinel-oxide mixture (ZnAl₂O₄/ZnO) obtained by thermal decomposition of a Zn–Al hydrotalcite at 1173 K with palladium nitrate solution. The samples, after thermal treatment in reducing conditions, were characterized by TEM and XRD. The catalysts showed a quite good catalytic activity in the reaction under study with high methanol conversion and good selectivity to CO₂. The high activity and selectivity were attributed to the prevailing presence, on the catalyst surface, of a highly dispersed 1:1 PdZn alloy phase.
