Abstract
FT-IR spectroscopy studies on the adsorption of pyridine on silica-supported heteropolyanions have shown the presence of surface acid sites, both Lewis and Bronsted ones, when starting from commercial phosphomolybdic acid, but only Lewis acid sites when starting from nhexylammonium phosphododecamolybdate. A preferential formation of propene instead of acetone (i.e., a larger selectivity towards dehydration) has been observed during isopropanol decomposition, due to the strong surface acidity of the samples.Keywords
