Description
In the present work, 27 kinds of metal oxides were employed as catalysts for the decomposition of sodium chlorate. Using the TPR (Temperature Programmed Reaction) method, we observed the decomposition temperature of sodium chlorate. One of the most effective metal oxide was prone to be nickel oxide. From the DTA (Differential Thermal Analysis)measurement, it was found that addition of metal oxides to sodium chlorate lowered the decomposition temperature to some extent, though the melting temperature did not change. Thus, the metal oxides added work as catalysts for the decomposition of the molten sodium chlorate, resulting in oxygen evolution at lower temperature.<BR>We discussed about the reaction mechanism betwe en the metal oxides and sodium chlorate. As the temperature rises, the hopping electrons are generated at the surface of the metal oxides, then the positive holes are formed. The chlorate ions are drawn toward the holes to be oxidized to perchlorate ions, which yield to sodium chloride and oxygen at the successive step. Thus, the decomposition temperature of sodium chlorate depends upon the activation energy of hopping electrons in the metal oxides.
