Aspects of the present application provides for enhanced catalytic materials, which can feature multiple functional and/or catalytic species, and methods of their formation. The materials can include catalytic nanoparticles (NPs) partially embedded within a supporting matrix. Treatment of the material, e.g., thermal, optical, microwave, plasma, and/or chemical treatment, can lead to the formation of functionally, e.g., catalytic or co-catalytic, relevant chemical and structural/morphological species or features at the NP-matrix, NP-pore, and matrix-pore interfaces. The treated material is characterized by enhanced properties, e.g., greater mechanical stability.

A silica-alumina based composite material for making hydroprocessing catalysts, is disclosed. The silica-alumina composite material generally comprises at least two silica-aluminas, the first being a modified first silica-alumina, and the second being a second silica-alumina that is unmodified or modified. The first silica-alumina is modified to comprise silica and alumina domains and a silica-alumina interphase. The second silica-alumina may also be modified at the same time or separately to comprise silica and alumina domains and a silica-alumina interphase. The first silica-alumina and the second silica-alumina differ in one or more physical and/or chemical characteristics, e.g., the ratio of silica to alumina, surface area, pore size, pore volume, silica domain size, or alumina domain size. The invention can be used for making catalyst base materials and catalysts useful for upgrading hydrocarbon feedstocks to produce fuels, lubricants, chemicals and other hydrocarbonaceous compositions.
