Direct catalytic valorization of ethanol either to olefins fractions C3-C8 or 1-butanol, 1-hexanol and 1-octanol over Au-Cu and Au-Ni containing catalysts was studied. Selectivity of 1-butanol formation was 75 %. First time ever over heterogeneous catalysts the reaction of ethanol and iso-propanol was carried on resulted in 3-methyl-2-butanol formation that is precursor of valuable monomer – isoprene. The peculiarities of the reaction mechanism are discussed, with the specific surface and electronic features of the prepared catalysts being considered. Found that growing the Au particles by forming the mixed MO/Au (M- Cu, Ni) particles resulted in an increased aim products selectivity
