Abstract

Abstract : Room temperature catalytic hydrogenation of sodium phenoxide is successfully realized by a Ru/TiO2 catalyst, where the electron-rich state of Ru and the interface of Ru and TiO2 are responsible for the enhanced activity. Abstract : Sodium phenoxide is a potentially promising hydrogen storage material due to its high hydrogen capacity and enhanced thermodynamic properties. Nevertheless, efficient catalysts are still lacking due to the high kinetic barrier for the reversible hydrogen uptake and release of sodium phenoxide. In the current work, a comparative study on the catalytic hydrogenation of sodium phenoxide was conducted. To our delight, a simple yet effective ruthenium-based catalyst was identified to respond aggressively to hydrogen in the solid-state hydrogenation of sodium phenoxide even at room temperature. The activity was enhanced by 6 fold with the as-synthesized 5.0% Ru/TiO2 catalyst as compared to that with commercial 5.0% Ru/Al2 O3, respectively, under the same conditions.
