Preparation, Characterization and Photocatalytic Activities of ZnO/TiO₂ Nanotube Composites

Abstract:

Highly dispersed ZnO/TiO₂ nanotube composites (NTCs) were successfully synthesized via a facile ethylenediamine-assisted deposition-precipitation route. This NTCs were characterized by XRD, TEM, and photcatalytic testing.The results revealed that hexagonal wurtzite phase ZnO NPs with an average size of about 2 nm were homogeneously dispersed and anchored on the surface of TiO₂ nanotubes (NTs) to form ZnO/TiO₂ NTCs, which exhibited excellent photocatalytic activity for photodegradation of methyl orange (MO) compared with P25 and Pure TiO₂ NTs. Furthermore, ZnO/TiO₂ NTCs possessed very favorable recycle efficiency due to their relatively high sedimentation rate and only slightly decrease of photocatalytic activity after a six- time recycle.
