Application
Ethylbenzene may be used as a starting material to synthesize:
- Acetophenone via selection oxidation in the presence of potassium dichromate supported on neutral alumina and using air as the oxidizing agent.
- Styrene via dehydrogenation over nanodiamonds in an oxygen-lean environment.

A novel nanodiamond/CNT-SiC monolith catalyst has been prepared by a facile two-step approach. The as-synthesized monolith afforded high activity and stability for ethylbenzene direct dehydrogenation to styrene, showing its potential application as a metal free catalyst in gaseous catalytic reactions.
