Abstract

<i style="mso-bidi-font-style:normal">P</i>6<i style="mso-bidi-font-style:normal">m</i>-type mesoporous silica (COK-12) prepared at quasi-neutral <i>p</i>H in a buffered medium using sodium silicate as a silica source has been used as a support to prepare a series of MoO₃/COK-12 catalysts with variable MoO₃ loadings by wet impregnation technique. Among these catalysts, 14 wt% MoO₃/COK-12 with small particle size of MoO₃ shows superior activity for the oxidative dehydrogenation of ethylbenzene to styrene in the presence CO₂.
