다국어 초록 (Multilingual Abstract)

TiO2-xNy nanoparticle was formed by employing the complex of titanium(III) chloride and ammonium hydroxide as a source of nitrogen. During calcination, an anatase phase of titanium oxide was formed and a part of oxygen in titanium precipitate was successfully substituted by nitrogen originated from strong interacted (or adsorbed) ammonium hydroxide on titanium precipitate. The resulting oxynitride photocatalysts absorb the visible light region, which suggests that the bandgap of TiO2-xNy is narrowed, comparing to that of titanium oxide. Although absorption region is like a small shoulder, TiO2-xNy photocatalyst has the photoactivity to decompose gaseous 2-propanol (IPA) under visible light irradiation. In this work, we investigate the mechanism to form TiO2-xNy and characterize its physical and chemical properties.
