As for the catalyst supporters for the synthesis of carbon nanocoils, an amount of different substrates have been reported by some researchers.Indium-tin-oxide glasses coated with Fe films were used to achieve high yield carbon nanocoils by Pan et al.Li et al.succeeded to use SiO2 substrates spin coated with Fe2 (SO4)3/SnC12 catalyst to efficiently synthesize carbon nanocoils.
