Sažetak
The role of FTIR speetroscopy in catalytic studies is briefly
discussed and some typical examples are shown. IR spectra of
weakly bound hydrogen on PtjSi02 reveal surface heterogeneity;
The hydrogen concentration on the surface is described by a Temkin isotherm. Adsorption of unsaturated C6 ring compounds on hydrogen poor Pt/Si02 is essentially a self'-hydrogenation process resulting in the formation of cyclohexane and carbon deposit on the metal surface. Chemisorption of n-hexane and benzene on hydrogen-rlch
Ni/Si02 surface gives identical spectra under similar conditions.
The same phenomenon is established for n-butane and benzene
after chemisorption on the hydrogen-poor surface. The infrared
and Raman spectra of C.H6 on NijSi02 suggested a symmetry lowering somewhere between C6v and C3v because of the nonplanarity of C6H6and the site symmetry of the surface.
