The ultrasonic treatment of Fe2-Bi-Mo2-Ox catalyst of ethylbenzene oxidative dehydration to styrene has been studied. Its physico-chemical properties have been compared with those of non-activated catalyst before and after operation. It has been shown that the catalyst prepared from salts solution activated by ultrasound has better activity and increases styrene yield under the same conditions.
