Estudo do efeito do cloreto em catalisadores de paládio usando a análise no infravermelho e de fotoelétrons excitados por raios X
Cunha, Eduardo V. da; Faccin, Flavio; Moro, Celso Camilo; Benvenutti, Edilson Valmir; Castro, Sandra C. de (2002) [Artigo de periódico]Chloride poisoning is known as having an inhibitor effect in the activity of metal catalysis. In this work in situ infrared spectroscopy (FTIR) of adsorbed carbon monoxide and x-ray photoelectron spectroscopy (XPS) were ... -
A FTIR study of the metal-support interactions and hydrogen spillover on Pd/TiO2 and Ni/TiO2
Faccin, Flavio; Guedes, Fabiana Flores; Benvenutti, Edilson Valmir; Moro, Celso Camilo (2002) [Artigo de periódico]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 ...
