Abstract

The influence of mesoporous silica matrix on the thermolysis of ferric oxalate loaded into its pores was studied. A significant decrease in the onset of the thermal decomposition temperature of ferric oxalate was observed. The maximum of the second decomposition stage of ferric oxalate in argon atmosphere was also appeared to be shifted by 30-40°C when thermolysis occurred in pores. These effects were accounted for the amorphous state of ferric oxalate and enhanced reactivity of highly dispersed particles.
