ルイス酸を含む無水液体HF中におけるフッ素-グラファイト層間化合物の合成

抄録

Highly fluorinated graphite has been prepared in anhydrous liquid hydrogen fluoride con-taining a Lewis acid. The products were stage 1, C_2.4F-C_2.0F 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 C_xF samples with large a₀ values. The C₁₅ and F_1s binding energies of C_2.4F to C_2.0F were higher than those of stage 1+2, C_2.7F-C_4.4F, and almost constant with a₀ values between 0.2470 and 0.2473nm.
