Synthesis of nickel-alumina aerogels was carried out by hydrolysis of aerogel precursors and mixture of aerogel precursors, followed by gelation and co-gelation of the sols, drying obtained alcogels under supercritical conditions, calcination and impregnation of alumina aerogels by nickel acetate. The aluminum isopropoxide and sec-butoxide and nickel acetate were used as precursors of nickel-alumina aerogels. The influence of type of precursor and solvent as well as nickel content on bulk density, specific surface area and total pore volume was investigated. Activity of the prepared aerogel catalysts was determined in cyclohexene hydrogenation.
