- Cobalt oxide based nitrogen-doped carbon nanotubes on diatomite were obtained.
- The resulting material was fund to be excellent catalysts for the oxidative carbonylation of amines with CO and air.
- The catalyst showed higher activity than Pd(OAc)2 under the same condition.
- The catalyst could be easily recovered and reused for several times with high activity.
Cobalt-nitrogen-doped carbon nanotubes stably supported on diatomite were obtained by employing Co(OAc)2/phenanthroline. The resulting material was found to be excellent catalysts for the carbonylation of a variety of amines with CO other than phosgene. Both high activity and selectivity were achieved in this carbonylation process, and it allows air as a cheap oxidizing agent. Moreover the catalyst could be recycled for several times with relatively higher activity compared to homogeneous catalyst palladium acetate.
