Electrochemical anodic oxidation of nitrogen doped carbon nanowall films: X-ray photoelectron and Micro-Raman spectroscopy study

Diameter effect of electrospun carbon fiber support for the catalysis of Pt nanoparticles in glucose oxidation

“…2A-C shows comparative XPS spectra of high-resolution narrow scans from the carbon region of CF 39nm , CF 158nm , and CF 309nm , respectively, after curve fitting using a mixed Lorentzian-Gaussian function. The measurement for the prepared CF 39nm reveals that the C 1s peak originates from significant sp 2 -hybridized graphite-like carbon atoms (284.2 eV) [25] and sp 3 -hybridized diamond-like carbon atoms (284.9 eV) [25] and one weak peak for O-C@O (289.2 eV) [26,27]. Both XPS results for CF 158nm (Fig.…”

Morphology, Microstructure, and Hydrogen Content of Carbon Nanostructures Obtained by PECVD at Various Temperatures

“…Figure 5(a) shows the survey spectra with the identified elements, carbon, oxygen, and nitrogen, and their relative atomic concentrations in the inset. The oxygen and nitrogen incorporation could occur during synthesis [33] at moderate vacuum and also during the contact with the environment. We note that the relative concentration of carbon increased from 89.0 to 93.6%, as temperature increased from 873 to 973 K, at the expense of the decrease of the atomic oxygen from 9.3 to 5.4% and of the nitrogen from 1.7 to 1.0%.…”

Surface modification of graphene and graphite by nitrogen plasma: Determination of chemical state alterations and assignments by quantitative X-ray photoelectron spectroscopy

“…Before discussing a recently published set of data [5,14,40,41,47,48,[53][54][55][56][57] of surface treated nanocarbon materials, depicted in Fig. 7 (and in Table 1 in the Supplementary Information), several problems associated with the published peak-synthesis procedure and the following assignments have to be emphasized.…”
