摘要：
ZnO tubes with diameter of 1 similar to 2 mu m and wall thickness of ca. 200 nm were synthesized by a simple hydrothermal method using polystyrene (PS) microspheres as the template. Results from SEM and XRD show that the concentration of zinc acetate and hydrothermal time plays an important role in the formation of ZnO tubes. The growth mechanism is proposed. The band gap value calculated from a UV-Vis absorption spectrum of ZnO tubes is 2.96 eV. The as-synthesized ZnO tubes exhibit high photocatalytic activity for the photodegradation of Rhodamine B under UV-light irradiation.
