英文摘要	the high-temperature durability of cordierite honeycomb rh-free three-way catalysts (twc) containing additives has been studied by calcining catalysts at various temperatures in the interval of 600 similar to 1100 degrees c. the three-way performances of these catalysts were evaluated for the reaction of carbon monoxide(co), hydrocarbon(hc) and nitrogen oxides(nox) at given conditions by using a tired bed reactor. the results show that after rh-free twc are thermally aged in air at 1100 degrees c for 5 h and 950 degrees c for 104 h, the twc still have better three-way activity compared with rh-containing twc.
