Template-free single-step electrochemical synthesis of ZnO hollow nanospheres: Self-assembly of hollow nanospheres from nanoparticles

摘要

The present work demonstrates for the first time a template-free, single-step electrochemical method to synthesize ZnO hollow nanospheres with diameter in the range of 20-200 nm, which are formed by self-assembly of ZnO nanoparticles of <10 nm diameter.
