How to separate CO2 into C and O2, how can this be done, will this require, much energy?
Heat it, it takes 393.5 kJ/mol.Jacquesl said:How to separate CO2 into C and O2, how can this be done, will this require, much energy?
Oxygen is produced when light is present.
you could heat CO2 over a catalyst of iron doped zeolite and hydrogen to produce water and ethylene
Jacquesl said:If hydrogen exist 75% in space, can it be used by tapping into that source
PaulS1950 said:Don't the CO2 scrubbers in re-breathers and in spacecraft use activated charcoal to capture the carbon and release the oxygen?
Borek said:Speaking of crackpottery... you can use tweezers to separate carbon and oxide. Just pull in opposite directions.
This statement makes no sense. An AFM does not, for instance, shoot out a laser beam at the sample.Eriqire said:If you used a focused light beam (laser) it would (theoretically) be plausible (with an atomic force microscope)

chemisttree said:Oxygen can be isolated but carbon monoxide is the final carbon containing product.
DrStupid said:How about the Boudouard reaction as a second step:
1. 2 CO2 -> 2 CO + O2
2. 2 CO -> CO2 + C
chemisttree said:Sure, if your goal is to produce carbon.
DrStupid said:According to the title of this thread it is.
chemisttree said:Of course it is but you were responding to my post which featured links where the final carbon-containing species was CO (as I indicated).
The most common method for separating CO2 into C and O2 is through a process called electrolysis. This involves passing an electric current through a solution of CO2, which causes the CO2 molecules to break apart into carbon and oxygen atoms.
The equipment needed for separating CO2 into C and O2 includes a power source, electrodes, and a container for the CO2 solution. The electrodes can be made of various materials, such as platinum or graphite, and the container can be made of glass or other non-reactive materials.
Yes, there are other methods for separating CO2 into C and O2, such as using chemical reactions or high temperatures. However, these methods may be more complex and less efficient compared to electrolysis.
The main purpose of separating CO2 into C and O2 is to obtain pure carbon and oxygen, which can then be used for various industrial processes. Additionally, this process can also help reduce the amount of CO2 in the atmosphere, which is a major contributor to climate change.
While separating CO2 into C and O2 can have environmental benefits by reducing atmospheric CO2 levels, the process itself can also have negative impacts. The electricity used in electrolysis may come from non-renewable sources, and the byproducts of the process, such as hydrogen gas, can also contribute to air pollution. Therefore, it is important to consider the overall environmental impact of the process before implementing it on a large scale.
