| description | The production of sorbitol from biomass, and especially from its cellulosic component, has been studied as a sustainable method for producing platform molecules. Because it requires two steps, namely, hydrolysis and hydrogenation, bifunctional materials are required as catalysts for this transformation. This study reports a bifunctional catalyst composed of sulfonic functions grafted onto a carbon support for the hydrolysis step and RuO<sub>2</sub> nanoparticles for the hydrogenation step. As sulfur can easily poison Ru, synthetic optimization is necessary to obtain an efficient bifunctional catalyst that surpasses a mere Ru/C catalyst. Kinetic studies highlight the better activity of the bifunctional catalysts compared to the reference monofunctional catalysts. Besides being active in hydrolysis reactions, sulfonic functions also have a role in avoiding the degradation of the sorbitol produced. The recyclability of the bifunctional catalyst is also superior to that of the monofunctional one. |
