Abstract: Catalysts are disclosed having metal oxide support structures and acidic reaction sites. Those reaction sites may have multiple bromine atoms bound to an aluminum atom with that aluminum-bromine group having an associated hydrogen ion. Additional structural features of the reaction sites are dictated by the aluminum oxide based catalysts and a silicon oxide based catalyst selected.

Abstract: Catalysts are disclosed having metal oxide support structures and acidic reaction sites. The reaction sites may be according to the general formula MxOyAlBrzX]−H+ where x is one or two; y is one or two; z is one or two; X is selected from Br or Cl; M is Al or Si and one or more of M, O and Al has a molecular bond with the metal oxide support structure.

Abstract: The present invention relates in part to a method of fabricating multimetallic nanoparticles, the method comprising the steps of providing a substrate; activating the substrate surface; adsorbing a cationic transition metal complex onto the substrate surface to form a substrate-supported cationic transition metal complex; adsorbing an anionic transition metal complex onto the substrate-supported cationic transition metal complex to form a substrate-supported multimetallic complex salt; and reducing the substrate-supported multimetallic complex salt to provide a plurality of multimetallic nanoparticles. The invention also relates in part to a composition of multimetallic nanoparticles comprising at least two metals Ma and Mb; wherein the ratio of Ma to Mb is between about 2:1 and about 1:2.

Abstract: Methods of preparing an acidic catalyst are disclosed that include heating a metal halide to produce a vapor phase metal halide, contacting an initial support material with the vapor phase metal halide in a reaction vessel causing a first chemical reaction and producing an intermediate acidic catalyst, contacting the intermediate acidic catalyst with HBr causing a second chemical reaction and producing an acidic catalyst product which is both more acidic than the intermediate acidic catalyst and more acidic than the initial support material.
