Universal and Versatile Route for Selective Covalent Tethering of Single-Site Catalysts and Functional Groups on the Surface of Ordered Mesoporous Carbons

A universal and benign strategy for the surface functionalization of OMCs through lithium-mediated chemistry has been reported. For this purpose, a hard templating method for the facile synthesis of monodispersed ordered mesoporous carbons (OMCs) with well-defined morphology templated from large pore mesoporous silica nanoparticles (l-MSN) has been used. These OMCs have high surface areas (800–1000 m2g–1) and large pore sizes (4–6 nm) suitable for anchoring bulky inorganic complexes. It has been demonstrated that the numerous defect sites present in the graphitic structure of OMCs can be effectively utilized for selective and covalent tethering of functional groups and single-site catalysts through lithiation of OMCs. Accordingly, for the first time a copper-based single-site oxidation catalyst has been covalently anchored onto the surface of OMCs. This novel system has been thoroughly characterized with advanced techniques such as electron microscopy, Raman spectroscopy, thermogravimetric analysis, X-ray...
