Solution cast films of C-60 on gold and glassy carbon substrates were studied in aqueous solutions as possible electrode materials. These films could be reduced in 1 M NaOH solutions to became conductive, possibly due to the formation of NaxC60. The reduced films were quite stable even on exposure to air, and their conductivity decreased only after a long time or when they were oxidized electrochemically. Both the reduction and the oxidation were completely irreversible. If oxidation is avoided, i.e. the potential is kept below +600 mV/SHE, these films can be used as electrodes, displaying individual properties as electrocatalysts; some electrochemical reactions were faster and others were slower than on bare gold or glassy carbon electrodes.
