1. A FTIR study of the metal-support interactions and hydrogen spillover on Pd/TiO2 and Ni/TiO2
Nickel and palladium dispersed on titania support were submitted to reductive treatment, under hydrogen, at 200 and 500 ºC. After the reductive thermal treatment the materials were exposed to carbon monoxide (10 Torr) and analyzed in the infrared region. The increasing of the electronic density in the metallic d subshell, produced by the reductive thermal t

2. Estudo do Catalisador (10%Ni-1%Cu) suportado na oxidação parcial indireta do Etanol
In the present work, the reaction of indirect partial oxidation of the ethanol for production of H2 for fuel cells was studied in catalysts 10%Ni-1%Cu (% mass) on different supports (Al2O3, SiO2-50, SiO2-200, Nb2O5 and CeZrO2). The catalysts were prepared by coimpregnation, leaving from aqueous solution of the respective nitrates, dry and calcined. The oxide
