dc.description.abstractThe effects of physicochemical properties of Mn-Ti catalysts on O-3 conversion were examined. The catalysts were prepared by a wet impregnation method that gave manganese supported on various commercial sources of TiO2. The properties of the catalysts were studied using physicochemical techniques, including Brunauer-Emmett-Teller (BET) surface area analysis, X-ray diffraction (XRD), H-2 temperature-programmed reduction (H-2-TPR), X-ray photoelectron spectroscopy (XPS), and thermal gravimetric analysis (TGA). The O-3 decomposition tests of Mn-Ti catalysts with various manganese loadings revealed that the 10 wt% manganese catalyst exhibited optimal, excellent activity. The O-3 conversion and Mn valence state of the Mn-Ti catalysts were different, depending on the structure of the TiO2 source. Increasing the O/Ti surface atomic ratio in TiO2 increased the Mn3+ ratio. The Mn3+ ratio directly affected the O-3 decomposition activity of the Mn-Ti catalyst. When the Mn3+ ratio was the largest, the catalyst showed the highest activity in O-3 decomposition. The valence state of Mn exposed to the surface was a critical factor in O-3 decomposition by Mn-Ti catalysts.-
