[交流] XPS中N的binding energy

请问各位,氰基(-CN)的N的binding energy在什么位置?N2等离子体处理物体表面产生哪些基团?有文献的话最好,麻烦推荐下,先谢谢了。

yuzhejun1984(金币+2,VIP+0):你给出的结果跟我看到的一些相关文献有出入(我看到的N在398.4eV),还有你推荐的文献找不到(你写的参考文献格式能否详细点),但还是谢谢你。 9-15 11:03
氰基(-CN)的N的binding energy 大概在400.8 eV 左右。N2等离子体处理物体表面产生基团有(N)i or (NO)O and (NO)i or (NO2)O, respectively. (N)i is an interstitial N in the middle of the interstitial space; (NO)O is NO sits at the substitutial site for the lattice O; at the same, (NO)i and (NO2)O are the interstitial NO and NO2 sits at the substitutial site for the lattice O.

Nitrogen complex species and its chemical nature in TiO2 for visible-light sensitized photocatalysis

Abstract
A photocatalyst with high reactivity under visible-light has been desired to utilize solar irradiation or interior lighting efficiently. Nitrogen-doped TiO2 revealed significant improvement in optical absorption and photocatalytic activity over TiO2 under visible light. We have performed the first-principles calculations to study the detailed N complex species introduced in TiO2. The results include stable geometries, densities of states, formation energies, and core levels. The present systematic studies account for the long-term controversial issue on N-doped TiO2, in particular, regarding the detailed assignment of N 1s binding energies observed in the XPS measurement. The detailed analyses of the formation energies show that introducing the N species more in a controlled way via process conditions is crucial to achieve the optimized photocatalytic performance.

Keywords: Photocatalysis; Titanium dioxide; Firt principles calculation; Nitrogen; Doping; X-ray photoemission spectroscopy
