I hear that when people get to O.C., they switch majors because they can't deal with it and that it's too hard. Is this true?

I would like to know whether CO2 can be ionized to beak it down into pure carbon and pure oxygen by heating, and whether that would occur at a low enough temperature that it could then be filtered to separate carbon from oxygen. Maybe the constituents could be seperated using an electric field?
