Synthesis of S and N Co-Doped Mesoporous Titanium Oxideby Anodization Processs

Abstract

Uni-directionally arranged mesoporous titanium oxide powders were prepared for titanium sheet through electrochemical anodization, one-step anodization with mixture of HNO3 and H2SO4 or two-steps anodization with HNO3 after H2SO4. The characterization of novel titanium oxide was carried out by XRD, XPS, SEM and TEM. The doping of S and N was confirmed with XPS evaluations during the anodization process in mixture of HNO3 and H2SO4. Furthermore, the S and N co-doped titanium oxide possessed the unique mesoporous structure.
