How can carbon dioxide be split into carbon and oxygen?

Splitting carbon dioxide (CO2) into carbon and oxygen can in fact be accomplished, but there is a catch: doing so requires energy. If hydrocarbon fuels, which produce the greenhouse gas in the first place, supply that energy, thermodynamics tells us that the net result will be more CO2 than you started with.

The closest you could try to do is to convert carbon dioxide into oxygen and carbon. Burning carbon (basically: coal) gives lots of energy. Splitting carbon dioxide requires (at least) that amount of energy. read more

Thus two oxygen atoms and 1 carbon atom form a double bond between them so more energy is required to break this bond. In this way $\ce{CO2}$ is formed. For converting $\ce{CO2}$ back into carbon and oxygen atoms, $\ce{CO2}$ should be heated at almost 298K so C becomes gaseous and oxygen becomes part of air. read more
