remove atmospheric co2 with buckyball emitters

Could we inject buckyballs into the atmosphere to remove CO2?

Could we use buckyballs to remove atmospheric carbon dioxide? I had this idea that we could throw lighter-than-air buckyballs into the atmosphere (they have buoyancy due to their shape), they bind to multiple CO2 molecules, get heavier than air and fall to the ground.

Is this possible? I'm not a chemist

Atmospheric Reactivity of Fullerene (C60) Aerosols https://par.nsf.gov...vlets/purl/10288934

       Thinking the simplest implementation is not the best, in this case.   

       Consider an internal combuckyon engine. Hot expansion, cool contraction Miller cycle, maybe. A cool buckyball dust is entrained with atmospheric or exhaust air and traps CO2, then the dusted-up air vents into a warming chamber where CO2-rich buckyballs expand from ambient heat and release their CO2 to be flushed by (not an expert, forgive me) a polycarbonate vapor adsorption matrix.   

       The buckyballs thus dissociated, dried as it were, of CO2 are then cycled again to the cool chamber to engage more CO2.

       No. C60 degrades on exposure to light, and the degraded form is carcinogenic when inhaled or ingested.   

       So... even if you could bankroll beaucoup buoyant buckyballs AND get them them bind with CO2 or other greenhouse gasses (both open questions) - there would be some unwanted consequences.

       Buckminsterfullerene doesn't bond with anything, it's a completely closed molecule. It's sometimes considered as storage material because other molecules can be contained within it, but they won't attach to it's surface.   

       As [A1] implies, when it bonds with anything, it does so by breaking the intact molecule.   

       Also, while buckyballs can be generic, it usually implies C60. You need to get up to very large fullerenes before they're lighter than air.
