“…Moreover, the vibrational modes of BF 4 À and BF 3 located near 800 cm À1 [26] are not observed, either because of the high conductivity of the compounds or the low content of these residues. For T T above 400 8C, a strong band, for which the intensity increases with increasing treatment temperature, is observed at 1212 cm À1 and is ascribed to covalent C-F bond [12,27] in accordance with NMR data. 19 F NMR spectra at room temperature of CF x (300) and of CF x (300) outgassed at 150 8C, then exposed to air 2 h and 12 h. …”

“…2 inset) testifies the existence of semi-ionic C-F bond [15]. Trace amounts of F atoms doped in the mesoporous carbon by semi-ionic C-F bond may tune the electric structures of carbon frameworks and serve as active sites for ORR [16].…”

“…If desired, considerable amounts of HF can be accrued within the graphite structure thereby approaching compositions of C 3.7 F(HF) 1.2 . Such compositions were obtained by the treatment of graphite with elemental fluorine and an oxidant such as K 2 PdF 6 in aHF [99][100][101]. Detailed electrochemical investigations have concluded that the presence of HF 2 À in the graphite impedes the conversion reaction during reduction and leads to poor utilization of the electrode material at higher rates.…”
