| Abstract |
Nanoparticle assemblies within hollow nanoshells provide access into advanced nanohybrids with unique and colligative properties. Herein, a simple and effective solution-based synthetic approach for peapod-shaped Au nanoparticle assembly embedded within hollow silica nanotubes (pp multi-Au@SiO2 NTs) is reported. Firstly, one-dimensional [multiple Au nanodot] core–[silica] shell nanowires (multi-Au@SiO2 NWs) are synthesized using reverse microemulsion techniques. A subsequent thermal treatment of multi-Au@SiO2 NWs in aqueous polyvinylpyrrolidone (PVP) solution results in the formation of pp multi-Au@SiO2 NTs. Further overgrowth of secondary materials (i.e., Pt) on the Au nanoparticles in pp multi-Au@SiO2 NTs results in the generation of [Au] core-[Pt] shell (Au/Pt) nanoparticle assemblies surrounded by silica nanotubes (pp multi-Au/Pt@SiO2 NTs). The obtained one-dimentional nanoparticle assemblies encapsulated within hollow silica nanotubes can be efficient and selective nanoreactors for targeted catalysis. |
