Ethanol was used as a reducing agent instead of NH₃ for the removal of NO_x.A series of Copper-supported catalysts were prepared via impregnation method.The effects of temperature and the support were studied.The reduction activity and texture of the catalysts were examined by TPR and BET methods.It was found that 10% CuO/TYZp-3 exhibited good catalytic activity at high temperatures,and the NO_x conversion reached 98.7% at 350;and 10% CuO/20% TiO₂-γ-Al₂O₃ showed good catalyic activity at low temperatures,and the NO_x conversion reached 46.4% at 250℃.And at above 400℃,the NO_x conversion over other CuO catalysts reached 99%.
