(a) XPS survey spectra of GO and N-rGO, and high resolution deconvoluted XPS spectra of N-rGO3 (b) C1s, (c) O1s, and (d) N1s. In addition, the atomic percentage of each element was determined from the XPS analysis of GO and N-rGO samples, listed in Table 1. The atomic percentage of nitrogen in N-rGO1, N-rGO2, and N-rGO3 samples was determined to be about 5.51, 4.53, and 2.80 at.%, respectively, which were consistent with theoretical values [49]. Each functional group identified in the XPS analysis of GO and N-rGO is also summarized in Table 2.
