The synthesis and characterization of sodium titanates (ST), and their evaluation in the photocatalytic reduction of nitric oxide (NO) are described herein. The materials were synthesized by a hydrothermal route using 5 M NaOH as the mineralizer agent and a TiO content of 0.06 mg/mL (expressed as the mass ratio of TiO/mL of NaOH), at 170 °C for 48 h, resulting in sodium tri- and hexa-titanates.
