Résumé
The catalytic hydrogenation of oxalic acid to glycolic acid (GA) and/or ethylene glycol (EG) has been identified as a promising route for producing value-added chemicals and potential hydrogen carriers. GA serves as a precursor for plastics and cosmetics, while EG can function as a liquid organic hydrogen carrier. In this work, we present an eco-friendly and scalable bottom-up approach to fabricate a Ru-based hydrogenation catalyst on θalumina-coated SiC foam. Nitrogen doping of the MOF(Al)-based template enhances the mechanochemical stability of the resulting alumina coating by significantly modifying its surface texture and morphology. This phasestabilization method enabled higher OA conversion compared to γ-alumina and yielded nearly equimolar amounts of GA and EG under continuous-flow conditions (120 °C, 50 bar). These findings demonstrate the potential of this synthesis approach for producing stabilized metal oxide phases with tailored morphologies that improve catalyst performance.
