TL;DR: Time-resolved in situ Raman microscopy has been applied to study the preparation of shaped Mo/Al(2)O(3) catalysts and a homogeneous distribution of Mo is obtained on a reasonable time scale.
The Role of Gold in Gold-Titania Epoxidation Catalysts
TL;DR: The adsorption behavior of propene, propene oxide, and related species on titania and gold–titania is investigated by use of IR spectroscopy to get a better understanding of the events on the catalyst surface, and to allow the development of a reaction mechanism and a better catalyst.
Infrared and Raman spectroscopic study of pH-induced structural changes of l-histidine in aqueous environment
TL;DR: In this paper, a complete and complementary set of vibrational data has been obtained that can be used to determine all possible states of protonation of histidine, i.e. H 4 His 2+, H 3 His +, H 2 His 0, HHis − and His 2−.

Hydration effects on the molecular structure of silica-supported vanadium oxide catalysts: A combined IR, Raman, UV–vis and EXAFS study
TL;DR: The effect of hydration on the molecular structure of silica-supported vanadium oxide catalysts with loadings of 1 −16 wt.% V has been systematically investigated by infrared, Raman, UV-vis and EXAFS spectroscopy as discussed by the authors.

Mechanistic study into the direct epoxidation of propene over gold/titania catalysts.
TL;DR: The epoxidation of propene over gold/titania based catalysts was investigated using different techniques and a kinetic mechanism is proposed by combining the information from different techniques.
