If carbon causes many clean atmospheric particles to conduct heat as a chemical reaction, is it possible to reverse the process, isolating the carbon? What chemical reactions can occur without bonding the carbon atoms to something else?

Preferably, I would like to know what process should remove only the carbon atoms from various carbon-based gas particles common in the atmosphere and compress them into pure carbon gas molecules into a solid molecular structure, or even into liquid for that matter.

The difficulty with removing carbon from carbon dioxide is that it takes a lot of energy, but plants do it all the time with photosynthesis, using solar energy, and producing the oxygen we breathe. The carbon goes into making plant starches, for example, which we eat.
