Abstract

The present work analyses, in detail, the optimization of a sonochemical process with respect to concentration of precursor and power supplied in a system. This is due to that even a small change in power dramatically changes the high-energy conditions created with the bubble collapse. A model reaction that has been considered for this purpose involves the decomposition of Fe(CO)₅ in decalin solvent as this reaction is strongly influenced by the cavitation conditions. Sonochemical treatment of this carbonyl results in the formation of amorphous Fe₂O₃, which on heat treatment gives nanocrystalline Fe₂O₃. It has been observed that concentration and power density parameters play an important role to obtain higher decomposition of Fe(CO)₅ and hence higher yield of the amorphous Fe₂O₃ product. Also, using the experimentally observed results, a correlation (polynomial) has been developed.
