Tailor-Made Inorganic Nanopeapods: Structural Design of Linear Noble Metal Nanoparticle Chains

Authors


Abstract

original image

Pt@CoAl2O4inorganic nanopeapods (see picture) consisting of well-defined Pt nanoparticle chains embedded in CoAl2O4 are synthesized by the pulsed electrodeposition of Co/Pt multilayered nanowires into an anodic aluminum oxide (AAO) membrane and a subsequent high-temperature solid-state reaction between Co/Pt nanowires and AAO. The pulse durations for Pt and Co depositions control the size and separation of Pt nanoparticles.
