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.
