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.
