Abstract：
 A oxide material based of Fei and its producing way, belongs to inorganic catalyst material technique field, used as the faci material of motor waste air cleaning catalyst. The invention increase the activation at low temperature by the change of construction.(TPR low temperature restore scope: 120-200 degC) and heat stability(after worked in 900 degC, 20--40m/g, hole vacuum0.03--0.3cm/g, hole diameter5nm--20nm). The producing way takes template way, first solute the Fei salt and metal solution salt by water of no ion, mix them by rate, then mix the inorganic salt solution and surface activate solution, add precipitate dose, water heat at 50-100 degC, wash, dry, last, fire at 400-1000 degC, then we get the oxide material.
