Popis:	This study concerns investigations of catalytic activity of heteropolyacids: H4SiW12O40 and H5PMo10V2O40 and their cupric and ferric salts deposited on conducting polymer supports: polypyrrole (PPy) and poly(N-methylpyrrole) (PMPy). Redox and acid–base properties of these catalysts were determined using a catalytic test reaction––conversion of isopropyl alcohol. The results of catalytic studies together with analysis of conductivity and morphology of catalysts show the influence of factors mentioned above on the activity in parallel dehydration and dehydrogenation reactions of isopropyl alcohol.
