Abstract

The catalytic conversion of cellulose is one of the most promising ways for sustainable and clean production of chemicals and biofuels. Firstly, cellulose must be hydrolyzed and then glucose can be converted in reactions such as hydrogenation or hydrolysis. Nb2O5 catalysts have shown great potential in cellulose conversion, due to its acidic properties that promote the hydrolysis reaction. On the other hand, noble metal catalysts, such as Ni and Co, can promote the hydrogenation of glucose. However, the textural and the structural properties of the niobium oxide need to be optimized in order to resist pressure and temperature conditions applied in the biomass conversion reactions. Thus, this project aims to study the influence of the textural, structural and acid properties of the Nb2O5. Ni and Co particles will be impregnated on the niobium oxide surface to form a catalyst, which comprises acid and hydrogenation sites. The multifunctional catalysts formed by Ni/Nb2O5 and Co/ Nb2O5 will be evaluated in the cellulose conversion reactions.
