Although the origin of the 2nd graphitic peak is not well understood, it may be related to the amount of oxygen on the GC surface.Ī. However, the peak shapes of C 1s spectra of anodic oxidized GC after heat treatment at 1500 ☌ in argon atmosphere were almost the same as the C 1s of untreated GC. The ratio of the 2nd graphitic peak area in the C 1s spectrum increased as the electrical charge increased. The 2nd graphitic peak is normally located +0.7–+0.8 eV away from the original C 1s spectrum. However, it was found that the 2nd-carbon peak should also be taken into consideration in the curve fitting process in addition to the effect of asymmetric peak shape of carbon to obtain a consistent value of O 1s/C 1s. ![]() ![]() ![]() Consideration of the asymmetric peak shape of the C 1s spectrum is normally done in order to obtain precise curve fitting results. An XPS study of anodic oxidized glass-like carbon (GC) was conducted in order to investigate the inconsistency between O 1s/C 1s and oxygen concentration (Ocal.) calculated from the curve fitting results of the C 1s spectrum. ![]()
