Figure 5

Deconvoluted C 1s signal for CNT_H₂SO₄/HNO₃ sample. Each filling indicates another component: grey—sp² carbon (graphite like), orange—sp³ carbon (defects), red—C-O, pink—C=O, green—COOH, blue—sp² carbon with nitrogen, yellow—sp³ carbon with nitrogen, and brown—satellite. Red squares indicate experimental data and black line indicates an envelope.
