摘要: We demonstrate that mesoporous carbon without deposition of metal particles is a highly active catalyst. It exhibits both high activity and selectivity in oxidative dehydrogenation ethylbenzene to styrene, as well long catalytic stability when compared with activated carbon. Both the as-prepared coke formed during initial stage reaction play an important role performance. XPS IR techniques reveal surface oxygen functional groups are sites for reaction. The ordered structure beneficial mass transport exhibiting term contrast
