Synthesis and Photocatalytic Characterization of Zinc Oxide Nano-Screw / Nitrogen-doped Titania Nanocomposite Thin Films

Abstract

Novel superstructures of zinc oxide thin film with nano-screws superstructures were prepared via soft solution route without any polymer additives. The thin film of ZnO could be produced directly on the substrates. The zinc oxide thin film with nano-screws superstructures was composed with visible-light induced nitrogen doped titania nano-particles successfully. The ZnO nano-screws/TiO2-xNy composite film showed excellent photocatalytic deNOx ability and quantum efficient.
