This work seeks to characterize the behavior of sulfate species on the surface of mixed metal oxides containing tin and zirconium at varying molar ratios. It is hypothesized that these materials could optimize the selectivity and yield of a given reaction by effecting the distribution of catalytically active sites in order to avoid undesirable side products. In-situRaman spectroscopy is coupled with ATR-FTIR, XRD, and BET analysis in order to probe the effects of support composition and environment on the predominant sulfate chelation structure. Our findings suggest that a tridentate configuration of the dispersed sulfate species is preferred at dehydrated conditions for the entire range of catalysts, while a large number of different hydrated species are present for the various catalysts tested.
