Characterization of ZnO Nanotube Fabricated by the Plasma Decomposition of Zn(OH)2 Via Dielectric Barrier Discharge

Here, we report a new and rapid way to decompose Zn(OH)(2) for the fabrication of ZnO nanotube using dielectric barrier discharge (DBD) plasma initiated at ambient condition. X-ray diffraction, field emission scanning electron microscope and high-resolution transmission electron microscopy were employed to characterize the fabricated ZnO nanotube. The results show that hexagonal hollow tubes in a wurtzite phase are obtained. Compared to the ZnO powder prepared by the thermal calcination, the DBD plasma made ZnO nanotube shows an enhanced performance for H2S removal at low temperature.
