Notes:
The origin of inelastic scattering in ISS spectra at low energy ratios (E/E0 ≤ 0.3) is discussed, and a description of results from ISS and XPS experiments on well-characterized Co/ZSM-5 catalysts after calcination in air and reduction in H2, H2 + CO, or CO is given. These treatments show that the chemisorption of hydrogen on highly dispersed metallic Co and Fe causes shielding of the metal from ISS detection. Additionally, the presence of hydrogen, whether in a chemisorbed form or in other forms such as hydrocarbons or H2O, affects significantly the intensity of the inelastic scattering.
