Can ultracapacitors be used to split CO2 into carbon and oxygen?

[QUOTE="Charles Link, post: 6014716, member: 583509"] The calculation shows energy ## E=2.7 \cdot 10^{-18} ## Joules/molecule. At a temperature of ## T=200,000 \, K ##, thermal energy will break most of the bonds in these molecules. That is only an approximate calculation, and each of the bond energies will actually be 1/2 of what I used above. This is only approximate, but it basically says that ## CO_2 ## is a very stable molecule. One way of getting ## O_2 ## in a process with ## CO_2 ## is by photosynthesis: ## CO_2+H_2 O \rightarrow CH_2O+O_2 ##. There have recently been attempts to do this process artificially, but it hasn't yet been achieved on a large scale.
