Title: An infrared spectroscopy study of metal-support interaction on Pt/TiO2. The influence of hydrogen adsorption.
Author: Benvenutti, EV
Davanzo, CU
Abstract: 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 the presence of hydrogen at the bulk is shown to produce a strong absorption in the infrared spectral region. After NTR treatment, the hydrogen is strongly chemissorbed.
