Ah a good question. More chemistry related, but a good question.

A lithium hydroxide canister that you blow CO2 through will react with the CO2 to produce lithium carbide and pure oxygen.

This was the big problem on Apollo 13. The canisters they had on the lunar module were only designed for 2 men! They had to literally jury rig a square canister from the Apollo spacecraft to fit in around hole on the LEM!

By the way breathing doesn't take apart carbon dioxide. Our bodies use oxygen and produce carbon dioxide.

Anyway when you burn carbon, you get carbon dioxide among other things. You have no doubt noticed that a charcoal fire gives off heat. That heat is energy released as the carbon and oxygen bind. To take the carbon and oxygen apart again, you have to add a lot of energy back.

Unfortunately, oxygen is strongly attracted to carbon, and it's quite stable. The easiest way I know to separate them is with plants, which take the carbon out of carbon dioxide, and give off oxygen.

Use a plant to do it by photosynthesis.

When we breathe we do not separate the oxygen out of carbon dioxide. A plant does it but it requires sun energy. What results is O2 plus carbon, which is captured in carbohydrates, cellulose, etc.

Hello
Really oxygen separates from carbon dioxide in Kalvin cycle.
Kalvin cycle acts with sun ahain in the name of Photo santes.
But it is possible to separate oxygen from carbon dioxide with using large amount of energy in high temperature.
In this operation by using "Fe" catalyst and we obtain Carbon and relaies oxygen.
