%X Fe2O3, TiO2, CuO and ZnO powders were mixed according to the formula of (1-x)TiO2 xCuO-Fe2O3 or (1-x)TiO2 xZnO-Fe2O3 (x=0, 0.2 0.4, 0.6, 0.8,1), and well ball-milled with H2O for 3 h to ensure homogeneity of the powdered solids, then fired at 1200were reduced at 500℃ with hydrogen gas. The reduced samples were subjected to recalcination at 500℃ in CO2 atmoscopy and scanning electron microscopy. Different phases were formed after firing of Cu 2 or Zn2 substituted Fe2TiOs. Magnetization (Bs) of the formed phases after firing are very low corresponding to diluted magnetic semiconductors (DMS) and increases with increasing the substituted cations (Cu 2 or Zn2 ). The reduction of the fired samples enhanced the Bs values whereas the red liability increases with increasing the Cu 2 or Zn2 content. Samples show different tendency toward CO2 decomposition which is very important for environmental minimization for CO2.
