Intermittent microwave irradiation method

Also, comparison of preparation method on the catalytic behavior of perovskite oxides for liquid reaction was investigated. Kulkami et al [56, 57] prepared a series of Lai-xSrxFeOs catalyst for reduction of nitrobenzene to aniline by microwave irradiation method, finding that the activity is similar to that prepared by conventional methods. The advantage in using microwave method is that it does not involve intermittent grindings and calcinations at elevated temperatures.
