Abstract

Abstract : Stronger interaction created by B2 O3 modification mitigates the oxygen reactivity of FeO x, promoting styrene selectivity in the oxidative dehydrogenation of ethylbenzene. Abstract : Here, we report a visible promotion effect of the B2 O3 additive on FeO x /Si3 N4 catalysts in the oxidative dehydrogenation of ethylbenzene. The oxygen reactivity of FeO x was alleviated by the strong interaction between FeO x and BO x species, which suppresses the overoxidation of ethylbenzene and styrene to carbon oxides, thus promoting styrene selectivity.
