摘要

Abstract

Three dimensional (3D) flower-like basic zinc carbonate constructed by multilayered nanoplates were rapidly prepared at room temperature through the direct precipitation method coupled with membrane dispersion technology

and porous ZnO with similar structures could be obtained after calcining the precursor. The structural properties of the products before and after the calcining process were characterized by SEM

TEM and XRD. The supersaturation of the reaction system due to the membrane dispersion played an important role in the formation of uniform Zn

precursors. A plausible mechanism was proposed for the formation of the flower-like ZnO assembled by nanoplates composed of nanoparticles. The obtained ZnO microspheres showed excellent photocatalytic properties

which could be attributed to the open structure and remarkable amount of porous nanoplates.
