Nitrogen-doped amorphous carbon films (a-CNx) with varying nitrogen content, were prepared by a thermal decomposition method using a mixture of CH4 + NH3 under atmosphere. A slight shift of the C 1s core-level spectrum toward the higher binding energy (BE) side was detected in a-CNx as a function of nitrogen content. This was interpreted as a charge transfer between carbon and nitrogen atoms rather than as a shift of the Fermi level (EF). The C 1s peak shifts can be explained by the presence of two kinds of C{N local structures and the charge transferred bulk C{C compo- nents by nitrogen atoms. The two kinds of deconvoluted C 1s components could be well correlated with the two N 1s components. Two localized states were detected below the EF in UPS spectra of a-CNx, which could be assigned to defect bands. These defects played a significant role in the surface reactivity, and were stabilized in a-CNx. The adsorption and reaction of NO were carried out on a-CNx as well as a-C films. It was found that both defect sites and O2- species were responsible on a-C, while O2- species were selectively active for NO adsorption on a-CNx.

内容記述 | We investigated the effects of incorporating a very low percentage of nitrogen on the local and the electronic structure of amorphous carbon (a-C) using X-ray pho- toelectron spectroscopy (XPS) and ultra-violet photoelectron spectroscopy (UPS). Nitrogen-doped amorphous carbon films (a-CNx) with varying nitrogen content, were prepared by a thermal decomposition method using a mixture of CH4 + NH3 under atmosphere. A slight shift of the C 1s core-level spectrum toward the higher binding energy (BE) side was detected in a-CNx as a function of nitrogen content. This was interpreted as a charge transfer between carbon and nitrogen atoms rather than as a shift of the Fermi level (EF). The C 1s peak shifts can be explained by the presence of two kinds of C{N local structures and the charge transferred bulk C{C compo- nents by nitrogen atoms. The two kinds of deconvoluted C 1s components could be well correlated with the two N 1s components. Two localized states were detected below the EF in UPS spectra of a-CNx, which could be assigned to defect bands. These defects played a significant role in the surface reactivity, and were stabilized in a-CNx. The adsorption and reaction of NO were carried out on a-CNx as well as a-C films. It was found that both defect sites and O2- species were responsible on a-C, while O2- species were selectively active for NO adsorption on a-CNx. We concluded that nitrogen doping reduces defect density to stabilize the surface of a-C, while at the same time inducing the selective adsorption capability of NO. | |||||
