Oxidative dehydrogenation of ethylbenzene of Fe−Sb−O catalysts

The conversion and selectivity to styrene in the oxidative dehydrogenation of EtPh at 800 K has been foudn to depend on the x=[Sb]/[Sb]+[Fe] ratio in the catalyst, being the highest at x≅0.8. The observed increase in specific catalytic activity is probably caused by the formation of a solid solution of FeSb2O6 in the catalyst.
