Furfuryl alcohol is used inLysine and Vitamin C synthesis, this is obtained by furfural hydrogenation, for this reaction is used as, catalyst Cu-Cr, but this high toxicity has increased interest in studying catalytic systems to lessen the environmental impact [1]. In this research were studied catalysts Ir/TiO 2 , reduced at temperatures between 473 K and 773 K, finding the largest 773 K conversion, selectivity was furfuryl alcohol increases at higher temperature reduction, while at lower temperature is favored formation acetals due to acid sites on the catalysts. We found the presence of SMSI effect at high temperatures, as ascertained by chemisorption. The results of XPS realize the strong influence of the SMSI on the catalytic activity. Analyses by TPR showed the presence of acid sites on the catalysts which explains the changes in selectivity, due to the release of species from the pioneering metal used for the preparation of the catalysts.
