High Resolution Xps Spectra Of Ni Ncnt 8 0 A Ni 2p B C 1s

High Resolution Xps Spectra Of Ni Ncnt 8 0 A Niођ Download scientific diagram | high resolution xps spectra of ni ncnt 8.0 (a) ni 2p (b) c 1s (c) n 1s (d) o 1s. from publication: controllable fabrication of abundant nickel nitrogen doped cnt. High resolution xps spectra of ni ncnt 8.0 (a) ni 2p (b) c 1s (c) n 1s (d) o 1s. the n 1s high resolution spectrum fig. 3 c shows three prominent peaks at 398.5, 400.3, and 401.2 ev that corresponds to the pyridinic n, pyrrolic n and graphitic n respectively [51] .

High Resolution Xps Spectra Of A Ni 2p B S 2p Cођ High resolution xps spectra of ru@ni ncnt ac show that the n 1s peak can be as proved by the result of ni xafs spectra and ni 2p xps spectra 3.0 g ni ncnt was immersed into 5 ml. Almost all the reported mnm catalysts, such as ni 3 n ni [31,36], mo 2 n ni [32], and ni ni 0.2 mo 0.8 n [33], showed a small overpotential lower than 20 mv of her current density at 10 ma cm À2. Xps spectra from two sources of ni (oh) 2 were recorded. nickel hydroxide powder (61% ni) was purchased from alfa aesar (mass, usa). α ni (oh) 2 was supplied by inco limited. it was characterized by x ray diffraction from the (0 0 3) peak areas compared with the (0 0 1) peak area of β ni (oh) 2 and found to be 92% α phase. The high resolution xps spectra of c 1s, n 1s and o 1s have no obvious changes in the valence states after the her (fig. s13 a–d). however, in the mo 3d spectra (fig. s13 e), the peak at 229.1 ev is almost disappeared, which indicates the content of mo with low valence is decreased significantly.

From the o 1s spectra of ni co p (figure s4, supporting information), three peaks corresponding to m o, oh −, and p o were observed, with a minor portion of the p o peak. this, along with the xps p 2p spectra, suggests that oxygen in the ni co p prepared in this study is not bound to the phosphide structure.
