The catalytic effects of metal oxides on thermal decomposition reactions, III

The influence of structural and electronic defects in iron oxides on their catalytic effectiveness with respect to the thermal decomposition of potassium chlorate

Journal of Thermal Analysis and Calorimetry
Authors: W. K. Rudloff and E. S. Freeman

The catalytic activity of a series of iron oxides on the thermal decomposition of potassium chlorate was investigated by methods of thermal analysis. Structural and electronic defects were introduced into the oxide by doping, heat treatment in different atmospheres, and irradiation withγ-rays. These induced defects changed in a systematic way the conductive properties of the iron oxides and correspondingly, their catalytic activity. The results are consistent with ann-type semiconductive behavior of the oxides.
