Facile synthesis and characterization of ZnO nanoparticles grown on halloysite nanotubes for enhanced photocatalytic properties

Abstract We demonstrated herein that ZnO nanoparticle with sizes in the range of 3–5 nm grown on the surface of halloysite nanotubes (HNTs) could be facile prepared in large quantities through the seed-mediated growth process using ZnAc2·2H2O as the zinc source. Compared with the individually disper...
