COx‐Resistant Oxidative Dehydrogenation of Cyclohexane Catalyzed by sp3@sp2 Nanodiamonds towards Highly Selective Cyclohexene Production

COx‐Resistant Oxidative Dehydrogenation of Cyclohexane Catalyzed by sp3@sp2 Nanodiamonds towards Highly Selective Cyclohexene Production

Deep oxidation/dehydrogenation are longstanding problems for decades in catalytic oxidative dehydrogenation (ODH) of cyclohexane and other alkanes. Here we show a metal‐free catalyst of nanodiamonds (NDs) with unique sp3@sp2 hybrid structure that catalyzes COx‐resistant cyclohexane ODH with remarkab...

Zusammenfassung:Deep oxidation/dehydrogenation are longstanding problems for decades in catalytic oxidative dehydrogenation (ODH) of cyclohexane and other alkanes. Here we show a metal‐free catalyst of nanodiamonds (NDs) with unique sp3@sp2 hybrid structure that catalyzes COx‐resistant cyclohexane ODH with remarkable reactivity towards cyclohexene production. The selectivity of cyclohexene can reach as high as 67 % with significantly suppressed COx emission (
