Abstract

Micro-combustion initiated by dielectric barrier discharge plasma has been applied for the removal of carbon template to prepare urchin-like ZnO particles. The combustion is operated at atmospheric pressure and low gas temperature (less than 150 °C), and the template is fully decomposed and rapidly removed. The obtained urchin-like ZnO possesses two distinct morphologies: nanosheets and sub-micro rods. The unique morphologies form on ZnO hexagonal nuclei with the template effect of activated carbon.
