Abstract

Abstract: Research on pillared clays prepared from purified bentonite of Boyolali Central Jawa, Indonesia, and polycation Zr at various concentration and calcination temperature had been done. Effect of acidity characteristic and structure of resulting materials were studied. The nature of acidic site of the material was identified on the basis of FTIRspectra of pyridine adsorbed on ZrO2 - pillared bentonite catalysts. Analysis showed that increasing calcination temperature was followed by decreasing acidity and increasing ZrO2 content in the pillared bentonite accompanied by the increase of its acidity. FTIR spectra showed there was an intensity increase of the characteristic band of 1635 cm -1 that indicates a Bronsted acid.
