MnO -TiO catalysts (0, 1, 5, and 10 wt % Mn nominal content) for NH-SCR (selective catalytic reduction) of NO have been synthesized by the reverse micelle-assisted sol-gel procedure, with the aim of improving the dispersion of the active phase, usually poor when obtained by other synthesis methods (e.g., impregnation) and thereby lowering its amount.

Particularly, two TiO samples were obtained by means of as many template-assisted syntheses, whereas other two TiO samples were obtained by a greener template-free procedure, implying acidic conditions and, then, calcination at either 200 °C or 600 °C. In one case, anatase was obtained, whereas in the other three cases mixed crystalline phases were obtained.
