Description

Application

Carbon monoxide can be used in the following applications:

• Transition-metal-catalyzed carbonylation reactions.
• Insertion of carbon monoxide in metal-carbon bonds during copolymerization reactions.
• To grow single-wall carbon nanotubes (SWNT) via disproportionation reaction catalyzed by molybdenum particles.

Catalytic hydrogenation of carbon monoxide over transition metals catalysts to form hydrocarbons has been reported.
