Synthesis and Polymorphic Control for Visible Light Active TiO2 Nanoparticles Burtrand I. lee, School of Materials Sci. & Eng, Clemson Univ., Clemson, SC The SACS-NMP post-treatment is an effective method to extract lattice hydroxyls and nitrogen to be incorporated in the crystal lattice with enhanced VL absorption. The greater the number of lattice hydroxyls in the polymorphic titania, the lower the photocatalytic activity. The more nitrogen presents in SACS samples, the higher the photocatalytic activity. SACS-200 showed the best photocatalytic activity under VL irradiation among the prepared titania samples and P25. UV/Vis spectra of as-prepared titania samples and P25 Methyl orange degradation of SACS-200 compared to WACS-200 and commercial P25.
