摘要：

The activity of Mn-stabilized zirconia with a Mn content ranging from 5 to 50 mol-% in the complete oxidation of n-butane is investigated here. The structure sensitivity as a major factor governing the activity is proved. Multivalent Mn when present in the zirconia lattice in concentrations from 5 to 30 mol-% is found to accelerate the reaction rate to a greater extent than does bulk zirconia or bulk MnO2 present as extra lattice component. The role of the calcination temperature on the stability of the structure and its repercussions on the catalytic activity are also demonstrated here.
