dismantling???
you mean to use CO2 as a reagent? Or to reduce CO2, or... ?
Anyway, I have heard of tests using CO2 in a solar cell type way to make longer hydrocarbon chains, like mimicking photosynthesis. But other processes are tedious as carbon dioxide is the very stable most oxidised form of a single carbon "chain".
Electrochemical carbon dioxide reduction tests are also taking place, but to the best of my knowledge, no easy commercialised process is available yet.
Aside from photosynth.
