Synergy between Sulfonic Functions and Ru Nanoparticles Supported on Activated Carbon for the Valorization of Cellulose into Sorbitol

The production of sorbitol from biomass, and especially its cellulosic component, has been studied as a sustainable method for producing platform molecules. Because it requires two steps, namely, hydrolysis hydrogenation, bifunctional materials are required catalysts this transformation. This study reports catalyst composed sulfonic functions grafted onto carbon support the step RuO2 nanoparticles hydrogenation step. As sulfur can easily poison Ru, synthetic optimization is necessary to obtain an efficient that surpasses mere Ru/C catalyst. Kinetic studies highlight better activity compared reference monofunctional catalysts. Besides being active in reactions, also have role avoiding degradation produced. recyclability superior one.
