Abstract:

It was found that the catalyst aged under microwave radiation is much more active for H2O2 decomposition than that aged under conventional heating. Characterization of the catalysts showed that the above result could be interpreted by a hypothesis that orientation of ions (Co2+, Fe3+) in the solution was restricted by microwave electromagnetic field so that the surface of the catalyst is irregular.

Key words: Microwave, Catalyst synthesis, Solid surface, CoFe2O4
