A series of CrO x /Al 2 O 3 samples with various Cr/Al molar ratios (0.1-1.0) have been synthesized by the sol-gel technique from Al(C 3 H 7 O) 3 (aluminium isopropoxide) and chromic acid precursors. The synthesis applied allowed obtaining the final product in monolithic (nonfractured upon drying) form with no use of drying control chemical additives. All samples are characterized by thermal analysis, XRD, and TEM. The low temperature nitrogen adsorption measurements indicate the presence ofdoi:10.2478/v10063-011-0003-0 fatcat:azik4vhe75a6zb33eivfs7jhyq
