Scientific paper

The chemical in ambient air responsible for degradation of fullerenes is ozone. The destruction of C60 in toluene proceeds at least 5 orders of magnitude faster with O3 than it does with O2. Ozonation of C60 in toluene resulted in the formation of C60O, C60O2, and C60O3. Oxides were not formed when crystalline C60 was exposed to O3. C60O was destroyed when heated in ambient air. The long-term survival of C60 in nature seems to require an environment low in O3.
