Title: An Infrared Spectroscopy Study Of Metal-support Interaction On Pt/tio 2. The Influence Of Hydrogen Adsorption [estudo Por Espectroscopia No Infravermelho Da Interação Metal-suporte Em Pt/tio 2. A Influência Da Adsorção De Hidrogênio]

Abstract: The influence of the presence of hydrogen on Pt/TiO 2 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 the presence of hydrogen at the bulk is shown to produce a strong absorption in the infrared spectral region. After HTR treatment, the hydrogen is strongly chemissorbed.
