Abstract

The aim of this work was to study the one-pot synthesis of sorbitol via hydrolysis-hydrogenation of cellulose in the presence of Ru-containing composites based on H<sub>3</sub>PW<sub>12</sub>O<sub>40</sub> supported on ZrO<sub>2</sub> and Nb<sub>2</sub>O<sub>5</sub> (Ru-PW/ZrO<sub>2</sub> and Ru-PW/Nb<sub>2</sub>O<sub>5</sub>). The main parameters impacted the reaction rate and yield of sorbitol, i.e. reaction conditions and type of catalyst were investigated. Ru-PW/ZrO<sub>2</sub> systems were more active than Ru-PW/Nb<sub>2</sub>O<sub>5</sub>. The yield of sorbitol was found to depend on the activation temperature of PW/ZrO<sub>2</sub> and PW/Nb<sub>2</sub>O<sub>5</sub> which affected textural properties, the amount of acid sites and size of Ru nanoparticles. The highest 66% sorbitol yield was observed in the presence of 3%Ru-PW/ZrO<sub>2</sub> activated at 550 °C and 1/1 of weight ratio of cellulose/catalyst, 180 °C, 7 MPa hydrogen pressure. This catalyst was stable for three cycles of the reaction without lost of it's activity.
