Table 2 The intensity ratios of I D/I G in Raman spectra of carbon samples and the size of their graphitic carbon

From: Functionalization of Petroleum Coke-Derived Carbon for Synergistically Enhanced Capacitive Performance

Samples I D/IG a La (nm)
PCAC 0.91 4.6
PCHO 0.94 4.7
PCNC 0.95 4.8
  1. La the size of graphitic carbon
  2. a I D/I G was calculated by the intensity of D band and G band
