Describes the characterization and catalytic properties of mesoporous silica supported Cs-substituted tungstophosphoric acid salt (CS-TPS/MS) with improved dispersion of the active clusters compared to materials described previously in the literature. In particular, transmission electron micrographs and the activity results for a model alkylation reaction are presented as evidence for the enhanced dispersion and performance. In addition, demonstrates improvements in the physical and thermal stability of these materials with Cs substitution using various characterization techniques.
