The possible mechanism of nanotube formation in the process is studied. The reactive species hydrogen peroxide and nitrate can be selectively produced in a gas bubble discharge in liquid using argon plasma or air plasma, respectively. It is observed that hydrogen peroxide enhances only the formation of an oxide layer, while nitrate forms pores on this oxide layer. It is proposed that the nitrate determines the formation of nanoporous nanotubes, while hydrogen peroxide enhances the oxidation.We thank the Institute for Frontier Materials (IFM), Deakin University for project funding and for the SEM, TEM, XRD, and Raman facilities.application/pdfen-AU© 2017 WILEY-VCH Verlag GmbH & Coamorphous TiO2anodizationdielectric barrier discharges (DBD)nanostructuresplasma-treated water201710.1002/ppap.2016002192020-11-23
