Abstract
|
Researchers
determined that molecular oxygen breaks into carbon nanotubes forming active
sites to abstract hydrogen from propane. Various carbonaceous species on carbon nanotubes were identified and
their effects on the oxo-functionalization as well as the catalytic
performance in the oxidative dehydrogenation of propane were examined. Results
suggested a certain amount of accessible skeleton defects to be beneficial to
the selective introduction of ether and ketonic carbonyl groups.
However, amorphous carbons are poorly selective during oxo-functionalization and the related functionalities decomposed easily during the long-term catalytic test. |
