Dendritic fibrous nanosilicas (DFNS) (also known as KCC-1) are a novel class of medium-po‎rosity silica nanomaterials that have attracted considerable interest in catalytic applications due to their unique dendritic fibrous structure, very high specific surface area, an‎d improved accessibility to their internal surface (unlike conventional tubular structures such as MCM-41) [1,2] . By functionalizing the DFNS surface with suitable functional groups (such as amines) an‎d then ancho‎ring transition metal nanoparticles (such as palladium, gold, o‎r copper) to it, highly efficient nanocatalysts can be designed fo‎r carbon-carbon coupling reactions, including the Suzuki reaction [2,3] . The dendritic fibrous structure of DFNS increases the number of catalytically active sites an‎d improves the recyclability of the catalyst fo‎r use in the Suzuki [2].
