Estudo por espectroscopia no infravermelho da interação metal-suporte em pt/tio2 : a influência da adsorção de hidrogênio

Benvenutti, Edilson Valmir; Davanzo, Celso U. (1999) [Artículo de periódico]

The influence of the presence of hydrogen on Pt/TiO2 catalysts submitted to reduction treatment has been studied by FT-IR at room temperature. After submitting to LTR treatment, the hydrogen spillover has been detected and ...
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) [Artículo 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 ...
