Examples of oxidation of hydrocarbons in the presence of carbon nanotubes Cumene

Reaction network of cumene with carbon nanotubes as catalysts.

Carbon nanotubes (CNTs) can catalyzes benzyl alcohol (BzOH) to benzaldehyde (BzH). A reasonable mechanism for the liquid-phase oxidation of BzOH on CNTs is proposed. Electron transfer in graphene skeletons plays an important role. Carbon catalyst displays outstanding recyclability. Nitrogen doping efficiently enhances the catalytic activity of CNTs for BzOH to BzH. Benzyl alcohol

Plausible mechanism pathway of BzOH oxidation with O 2 over CNTs.

They are AcPO (target product), 1-phenylethyl alcohol (PEA), 1-phenylethyl hydroperoxide (PEHP), benzaldehyde (BA) and benzoic acid (BzA), which were identified by GC–MS Ethylbenzene
