摘要:

In our previous work, POM has been investigated by the pulse reaction with CH4 and CH4/O2 respectively, on Rh/SiO2 catalyst. Kinetic isotopic effect was also studied by using CD4 and CD4/O2. The results suggest that POM may proceed most possibly via a mechanism of surface carbon species reacting with surface oxygen. In the present work, 1H MAS NMR was utilized to investigate the POM mechanism in aiming of presenting additional evidence.
