Abstract:In catalytic reactions, the diverse binding sites of nanometals located in nanomaterials considerably influence the activity of nanocatalysts. In this study, the special nanostructure and charge distribution of halloysite nanotubes (HNTs) incorporating a weak reducing agent closo-dodecaborate (closo-[B 12 H 12 ] 2− ) were leveraged to immobilize Au nanoparticles (NPs) on the inner and outer surfaces of HNTs. The introduction of closo-[B 12 H 12 ] 2− into HNTs was achieved via vacuum extraction and acid immersi… Show more
