Carbons modified with fluorine [112] and nitrogen [113,114] have also been extensively studied as catalysts in fuel cells leading to improvements in performance for both oxygen reduction and methanol oxidation. Both decrease in overpotentials and increase in lifetimes have been reported. The application of similar concepts to electrode materials for effluent/water treatment is likely to lead to electrodes with greater stability. A nitrogen-doped diamond-like carbon has been shown to be effective for generation of ozone in water and the resulting solution employed to sterilize water oiEscherichia coli [115].

Ternary materials that incorporate carbon into a boron-nitrogen framework are expected to exhibit extreme hardness as a result of their diamond-like structures. Alkyl-, vinyl- and alkynyl-substituted borazines are potential... 

Figure 22 shows RBS spectra of amorphous (Raman spectra similar to amorphous diamond like films) carbonitride films deposited at different temperatures using IBAD. Using this technique, maximum nitrogen incorporation was 33% as compared to 57% required for P-C3N4 stoichiometry. The XPS spectra (C Is and N Is) of the film with 33% nitrogen are shown in Figure 23. From these spectra the percentage of single bonded carbon and nitrogen is obtained...

White powder, hexagonal graphite-like form or cubic crystal cubic form similar to diamond in its crystal structure, and reverts to graphite form when heated above 1,700°C density 2.18 g/cm melts at 2,975°C (under nitrogen pressure) sublimes at 2,500°C at atmospheric pressure insoluble in water and acid attacked by hot alkalies and fused alkali carbonates not wetted by most molten metals or glasses.
