Abstract
Porous nanozinc oxide (ZnO) was successfully fabricated by a facile infiltration and calcination method with the help of a China rose petal template. The as-prepared products were studied by X-ray powder diffraction, field-emission scanning electron microscopy, and transmission electron microscopy (TEM). X-ray diffraction results proved that the as-prepared product was the hexagonal phase of ZnO without any impurity. Both SEM and TEM images showed that the biomorphic structures of ZnO were constructed with many regular nanoparticles with diameter of about 20 nm. The as-synthesised porous nanoZnO displayed excellent waste water treatment performance with high removal capacities toward methyl orange. This novel biotemplate process provides an economical and environmentally friendly route to obtain advanced assembling biomorphic nanoarchitectures, and will make it possible for their potential application in the field of catalysis and other.
