Summary, etc. <p>Anew series of bimetallic Ni-Co catalysts, prepared by step wise substitution of Ni by Co, in mono metallic Ni (8%)/ CeO<sub>2 </sub>-Al<sub>2</sub>O<sub>3</sub>,withthe compositions of 6%Ni-2%Co, 4%Ni-4%Co, 2.5%Ni-5.5% Co and 8% Co, have been evaluated for conversion of ethanol to butanol and higher alcohols according to Guerbet alcohol chemistry.XRD, TPR and XPS studies reveal the formation of Ni-Co alloys at specific bimetallic compositions. Maximum reducibility is observed for the composition 4%Ni-4%Co,which also displays maximum ethanol conversion (55.1%) with C<sub>4+</sub> alcohols selectivity of 50.2%, which are higher than those realized for mono metallic Ni and Co catalysts. Ni-Co alloys in bimetallic catalysts promote the crucial ethanol dehydrogenation and C<sub>4</sub> and C<sub>4+</sub> aldehydes hydrogenation steps in the Guerbet process, there by increasing ethanol conversion and C<sub>4+</sub> alcohol selectivity. Selection of bimetallic catalysts with specific compositions seems to be one of strategies to improve ethanol conversion and higher alcohols selectivity.</p>
