Fig. 5. (Color online) X-ray photoelectron spectroscopy of the synthesized Ni–graphite CSNPs according to the C₂H₂ flow rate: (a) C 1s of the Ni–graphite CSNPs before and after the synthesis; (b) O 1s of the Ni–graphite CSNPs before and after the synthesis; (c) peak intensity of the C–C bonds; and (d) atomic percent by element.
