Abstract
Zirconia-phosphate aerogels were prepared by two methods: a one-step s ol-gel synthesis followed by supercritical drying and an incipient wet ness impregnation synthesis of a calcined zirconia aerogel. These samp les were characterized by nitrogen adsorption, X-ray diffraction, infr ared spectroscopy, and 1-butene isomerization. We identified both the conditions when zirconia-phosphate aerogels possess Bronsted acid site s, and the phosphate species responsible for their generation.
