Abstract
Highly fluorinated graphite has been prepared in anhydrous liquid hydrogen fluoride con-taining a Lewis acid. The products were stage 1, C2.4F-C2.0F with α-axis lattice parameters, a0=0.2470-0.2473nm. It was found that MoF6 is more effective than SbF5 as an oxidizer of graphite and the relatively low temperatures such as 8 to 18°C are preferable to yield the CxF samples with large a0 values. The C15 and F1s binding energies of C2.4F to C2.0F were higher than those of stage 1+2, C2.7F-C4.4F, and almost constant with a0 values between 0.2470 and 0.2473nm.
