A new pathway for the catalytic wet oxidation (CWO) of glucose is described. Employing a cationic Ru@MNP catalyst, succinic acid is obtained in unprecedently high yield (87.5 %) for a >99.9 % conversion of glucose, most probably through a free radical mechanism combined with catalytic didehydroxylation of vicinal diols and hydrogenation of the resulted unsaturated intermediate.
The inherent properties of a single atomic carbon layer in graphene offer new opportunities for the creation of catalytically active centers tailored on a molecular level on a support with high thermal stability, as well as outstanding mechanical properties and specific surface area. We demonstrate that organization of the two-dimensional system of the carbon layer into threedimensional (3D) graphene-like catalytic materials with connectivity of a pore network providing good accessibility to the active centres allows the preparation of a conceptually new class of catalytic materials exploiting graphene properties. In this study, 3D graphene-like microporous carbons, denoted as β-graphene and Y-graphene, were synthesized by nanocasting of beta ( * BEA) and faujasite (FAU) zeolite templates. Structural analyses show that the materials are characterised by 3D assembled and highly stable single atomic graphene layers forming an open porous system resembling the regular channel system of the zeolites with a specific surface area comparable to the surface area of graphene. The materials effectively catalyse the hydrogenation of alkenes, alkynes and cycloalkenes into the corresponding alkanes and cycloalkanes. The materials facilitate catalytic intramolecular rearrangements including the selective isomerisation of double bonds and branching of linear chains, as well as stereo-selective isomerisation of unsaturated hydrocarbons.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
