Preparation of floral-patterned ZnO/MWCNT heterogeneity structure using microwave irradiation heating method

摘要

HNO_3-treated multi-walled carbon nanotubes enclosed by flower-like zinc oxide particles were prepared by a microwave irradiation heating method. The product was characterized by X-ray diffraction and scanning electron microscopy. It was found that the flower-like zinc oxide grows around the multi-walled carbon nanotubes to form a floral-patterned structure. Multi-walled carbon nanotubes play a role as a template for the growth of ZnO and they can link ZnO particles together as a complex fabrication. This discovery is useful for nano-electronic applications.
