    摘要： Inorganic oxide substrates are functionalized with silicon-free organic functionalizing agents. The organic functionalizing agent has a bonding functional group for bonding to the substrate and a functionalizing moiety that is not bonded to the substrate for imparting a desired functionality to the substrate. The functionalized inorganic oxide substrates are manufactured by selecting a functionalizing agent and reaction conditions that allows the bonding functional group to bond to the inorganic material while leaving the functionalizing moiety available for providing the desired functionality. The functionalized inorganic oxides can be used as filler materials in polymers or to manufacture a supported nanoparticle catalyst.

    摘要： Organic ligands that contain at least one aryl group are immobilized on a solid support. The organic ligands are of the type used to form a catalyst complex suitable for carrying out a catalytic reaction, preferably an asymmetric reaction. To immobilize the organic ligands, a tethering group is bonded to the ligand using, for example, a Friedel-Crafts acylation or alkylation reaction. The immobilization of the organic ligand can be carried out using a single reaction with the organic ligand.

    摘要： Methods for manufacturing carbon nanostructures include: 1) forming a plurality of catalytic templating particles using a plurality of dispersing agent molecules; 2) forming an intermediate carbon nanostructure by polymerizing a carbon precursor in the presence of the plurality of templating nanoparticles; 3) carbonizing the intermediate carbon nanostructure to form a composite nanostructure; and 4) removing the templating nanoparticles from the composite nanostructure to yield the carbon nanostructures. The carbon nanostructures are well-suited for use as a catalyst support. The carbon nanostructures exhibit high surface area, high porosity, and high graphitization. Carbon nanostructures according to the invention can be used as a substitute for more expensive and likely more fragile carbon nanotubes.

    摘要： Reforming nanocatalysts are formed using a dispersing agent to increase the activity, selectivity and longevity of the catalyst when used in a reforming process. The nanocatalyst particles are formed using a dispersing agent having at least one functional group selected from the group of a hydroxyl, a carboxyl, a carbonyl, an amide, an amine, a thiol, a sulfonic acid, sulfonyl halide, an acyl halide, an organometallic complex, and combinations of these. The dispersing agent is particularly useful for forming multicomponent catalysts comprising an alloy, combination, mixture, decoration, or interspersion of platinum and one or more of tin, rhenium or iridium. The formation of the nanoparticles may include a heat treating process performed in an inert or oxidative environment to maintain the catalyst atoms in a non-zero oxidation state to thereby maintain a stronger bond between the dispersing agent and the catalyst atoms. Multicomponent reforming catalysts having anchored nanocatalyst particles exhibit particularly good activity, selectivity and longevity when used in the reforming of naphtha and/or formation of BTX.
