%X Cu-Mg-Al hydrotalcite mixed oxide was prepared by co-precipitation. The mixed oxide and its procurer were characterized by XRD. NO, storage performance and decomposition of the stored NO, over the catalyst were investigated by NO, storage experiment at constant temperature, temperature programmed desorption (TPD) and temperature programmed surface reaction (TPSR), respectively. The results indicate that Cu-Mg-Al hydrotalcite mixed oxide has a good performance of NO, storage. The formed nitrate can be decomposed to gaseous NOx rapidly in the investigated temperature range of 160-360 degrees C, and a small amount of gaseous NO, can be reduced by C3 H6 with increasing the concentration of C3 H6 in the inlet gas.
