制备了几种用于丙烯(C3H6)燃烧的铁酸钙基催化剂(Ca/Fe=0.33-3)。具有褐铁矿晶体结构的铁酸钙催化剂在250-450℃的温度范围内对C3H6燃烧具有催化活性。褐铁矿相(Ca2Fe2O5)是450℃以下表层氧物种(O-2(-))形成的原因。
Several types of calcium ferrite base catalysts (Ca/Fe = 0.33-3) for propylene (C3H6) combustion were prepared. Calcium ferrite catalyst with brownmillerite crystal structure provided catalytic activity for C3H6 combustion in the temperature range of 250-450 degrees C. The brownmillerite phase (Ca2Fe2O5) was responsible for the formation of oxygen adspecies (O-2(-)) in the surface layer below 450 degrees C.
