XPS spectra of thin CNx films prepared by chemical vapor deposition

Surface modification PVA hydrogel with zwitterionic via PET‐RAFT to improve the antifouling property

“…In the spectra of PVA hydrogel as shown in Figure , it exhibited two different components of C‐1s at 285.0 eV and 286.6 eV, which corresponding to carbon atoms CC/CH and carbon atoms with hydroxyl groups COH, respectively. The peak positions were in good agreement with previously reported binding energies of PVA …”

Effects of nitrogen doping on the structure of carbon nanotubes (CNTs) and activity of Ru/CNTs in ammonia decomposition

“…2). From the literature [21][22][23][24][25][26][27][28], N1s BEs of carbon nitride formed on solid carbon materials were found to be around 398 and 401 eV. The shift of BE in this investigation is ascribed to the different chemical environments for nitrogen atoms in various compounds and the relaxation effect in the measurement process [29][30][31].…”

“…The shift of BE in this investigation is ascribed to the different chemical environments for nitrogen atoms in various compounds and the relaxation effect in the measurement process [29][30][31]. According to the literature [24][25][26][27][32][33][34], p1 can be attributed to the tetrahedral C-N bonding with C in sp 3 hybridization and N in sp 2 hybridization states. The nitrogen atoms in this bonding state are located at the edge of the graphene sheet in the plane of the graphite and are referred to as pyridinic nitrogen [25][26][27]32].…”

Functionalization of nitrogen-doped carbon nanotubes with gallium to form Ga-CNx-multi-wall carbon nanotube hybrid materials

“…Carbon nitride (CN x ) films studied in previous works exhibit nearly identical bonding character as their curved CN x -MWCNT cousins, and both show characteristic peaks for the N 1s around 398 and 401 eV, with the peak at about 401 eV typically being the strongest [28][29][30][31]. The peak at about 398 eV is generally attributed to pyridinic nitrogen (three covalent bonds and one lone pair) while the 401 eV is attributed to substitutional nitrogen (four covalent bonds and a formal positive charge).…”
