FTIR study of the oxidation reaction of CO with O2 over bimetallic Pd–Rh/SiO2 catalysts in an oxidized state
Paulo Araya,Cristián Weissmann +1 more
TL;DR: In this article, the results show that the two methods of impregnation lead to the existence of oxidized Rh on the surface of the bimetallic catalyst, however, in the case of the sequential improglomeration method, the Pd surface is more reduced than in case of co-impregnation.

Using in situ IR Spectroscopy to understand selective alkylation of aromatics over zeolites
TL;DR: In situ IR spectroscopy in combination with kinetic measurements was used to clarify the mechanism of the methylation of toluene over zeolitic catalysts as mentioned in this paper, showing that the rate of methylation is directly proportional to the surface concentration of activated methanol species (methoxonium ions at low and methoxy groups at high reaction temperatures).

Ft-ir studies of complexone adsorption on oxide supports
TL;DR: In this paper, the adsorption of EDTA and its salts on γ-alumina and titania supports was investigated by transmission FT-IR and the results indicated that the observed changes in the properties of adsorbed chelates are mainly due to interaction of the chelate molecules with support hydroxyl groups.
