Sustainability criteria has boosted the interest of catalytic conversion of biomass-derivedfeedstocks. Ethanol (EtOH) is one of the most relevant potential sources of “bio”-carbon [1].Its use to get oxygenated chemicals instead of fuels avoids eliminating its oxygen contentsincreases the cost of the process. Acetaldehyde (AcH), an important chemical used as solventand intermediate for the synthesis of a wide range of organic compounds [2], can be obtainedby gas-phase catalytic oxidation of EtOH with oxygen (or air), an economical andenvironmentally friendly process. Vanadium oxides exhibit excellent catalytic properties forthis reaction, due to its versatility in terms of its variable oxidation states and coordinationgeometry [3] that depend strongly on their support. Due to their low cost and abundance, clayminerals can be an important alternative for the generation of catalyst supports, as theirproperties allow a very wide range of structural, textural and chemical modifications [4]. Thismotivated us to investigate the use of modified clays as a sustainable high surface areasupports for vanadium catalysts and their influence on their application for the said reaction.
