AB The present study optimizes Cu-supported catalysts on hydrotalcite for the synthesis of n-butanol whose interestis in its use as biofuel, due to its superior performance in comparison with other short-chain alcohols. Thecatalytic performance was improved by adding Nb to the catalytic formulation. In this way, several Cu-Nbcatalysts supported on hydrotalcites (Mg/Al) with different Nb loadings were synthesized by incipient wetnessimpregnation and characterized by H2 temperature-programmed reduction, X-ray diffraction, N2 physisorption,CO2 and NH3 thermo-programmed desorption and X-ray photoelectron spectroscopy. It was shown that theincorporation of Nb promoted a suitable balance between the acid-basic and redox sites, modulating the Cu0/Cu+dehydrogenation/hydrogenation properties for the n-BuOH production. The synthesis of multiple value-addedproducts (n-BuOH, acetaldehyde, ethyl acetate, and 1-hexanol) was achieved in both the liquid (at 180 ºC)and gas phase (150 350 ºC), where it was demonstrated that both the n-BuOH selectivity and ethanol con-version improved with the Nb addition. The performance of the catalysts under time on stream and theirrecycling is also described.
