Synthesis of cube–rod–tube triblock asymmetric nanostructures for enhanced heterogeneous catalysis

Abstract

A triblock asymmetric nanostructure composed of a core–shell Fe₂O₃@SiO₂ cube as the head, SiO₂ rod as the body and SiO₂ tube as the tail is fabricated via a sequential growth process combining solution–liquid–solid and droplet soft templating mechanisms, which can be used as a nano stir bar with accelerated catalytic performance.
