Can CO be Broken Down into Carbon & Oxygen?

In summary, breaking down carbon monoxide (CO) into elemental carbon and oxygen requires extreme temperatures and the use of a metal surface or a catalyst. This is because CO has a very strong bond, even stronger than nitrogen gas. However, by sequestering the oxygen and utilizing the crystallization and combustion energies, it is possible to overcome this bonding and break down CO into its elements. This can be achieved through a cycle of CO disproportionation at different temperatures.

Is there any known way, however expensive or inconvenient, to break CO down into elemental carbon and oxygen?

Could you ionize it using electricity?

having a metal surface helps too.

CO has the strongest bond of any known (or possible) molecular compound -- stronger even than nitrogen gas. Breaking it into elements requires extreme temperatures. I am a little surprised that it can be achieved with temperatures as low as 2000 K.

The molecule can be broken down by sequestration of the oxygen; the crystallization energy for gaseous carbon to graphite, and the combustion energy for many metals to oxides would provide driving forces that, taken together, could easily overcome the very strong bonding in carbon monoxide.

You are right, this is difficult in one step, but
CO disproportionates already at relatively low temperatures into C and CO2, although this requires some catalysator, as CO is thermodynamically unstable with respect to this disproportionation already at normal temperature. Hence generation of C is the trivial part. On the other hand, CO2 disproportionates at higher temperatures into CO and O2. Taken together this seems to me a perfectly viable cycle to decompose CO into C and O2.
 

Related to Can CO be Broken Down into Carbon & Oxygen?

1. Can carbon monoxide (CO) be broken down into carbon and oxygen?

Yes, carbon monoxide can be broken down into its constituent elements, carbon and oxygen, through a process called combustion. This occurs when CO reacts with oxygen in the presence of a catalyst, such as a flame or hot surface, to form carbon dioxide (CO2) and release energy.

2. What happens when carbon monoxide is broken down?

When carbon monoxide is broken down, it is converted into carbon dioxide, which is a more stable and less toxic compound. This process also releases energy, which can be harnessed for various purposes such as heating or generating electricity.

3. Is it safe to break down carbon monoxide into carbon and oxygen?

It is generally safe to break down carbon monoxide into carbon and oxygen, as long as it is done in a controlled setting with proper ventilation. However, carbon monoxide is a toxic gas, and any process involving its breakdown should be carefully monitored to prevent exposure to the gas.

4. What are the benefits of breaking down carbon monoxide?

Breaking down carbon monoxide has numerous benefits, including reducing its toxicity and creating a more stable compound (carbon dioxide). Additionally, the energy released during the process can be harnessed for various purposes, making it a useful source of energy.

5. Can carbon monoxide be broken down naturally?

Carbon monoxide can be broken down naturally through various processes, such as photochemical reactions in the atmosphere. However, these processes are relatively slow, and most of the carbon monoxide in our atmosphere is broken down through human activities, such as combustion in engines and industrial processes.
