Both substitutional and interstitial nitrogen-doped titanium dioxides (N-TiO2) were prepared. Their surface states were clarified by XPS spectra of N 1s, O 1s and Ti 2p. The results of photocatalysis show that both substitutional and interstitial N impurities greatly enhance the photoactivity of TiO2 in visible light. Moreover, the visible light activity of interstitial N-doped TiO2 is higher than that of substitutional N-doped TiO2. The microwave synthesis presented in this paper is a promising and practical method to produce interstitial nitrogen-doped photocatalysts with high visible light activity.
Both substitutional and interstitial N impurities can enhance the photoactivity of TiO2 in visible light; moreover, the visible light activity of interstitial N-doped TiO2 is higher than that of substitutional N-doped TiO2.Figure optionsDownload as PowerPoint slide
