Abstract

Styrene and benzaldehyde are manufactured by energy-intensive direct dehydrogenation and intermittent liquid chlorine oxidation batch process respectively. The co-production of styrene and benzaldehyde through selective oxidation of ethylbenzene is an environmentally friendly and economically feasible alternative. However, it is hard to control the selectivity of styrene or benzaldehyde as a result of deep oxidation reactions. Herein, we report an efficient selective oxidation catalyst, boron nitride-supported monomeric MoOx (MoOx/BN), over which styrene and benzaldehyde can be selectively co-produced. Structure characterizations and catalytic evaluations reveal that MoOx/BN catalyst is conducive to the generation of benzaldehyde and less formation of COx, compared with monomeric MoOx supported on inert silica. Based on the kinetic analysis, over MoOx/BN catalyst, styrene is the primary product and benzaldehyde is the major by-product in the subsequent oxidation reaction. The boron hydroxy groups of MoOx/BN catalyst are involved in the reaction network, which could regulate the reaction behavior of monomeric MoOx species; thus the reaction favorably generates more benzaldehyde.
