Carbon-based compounds are the basis for all living systems and comprise the structure of fossil fuels in the form of hydrocarbons. Peak Binding energy (eV) atom ic concentration assignm ents N 1s 399.76 2.45 0.03 Am ines O 1s 532.39 9.150. Table S1: atomic concentration derived from the XPS C1s, O1s, Si2p and C1s peak areas. Carbon’s small size allows it to form multiple bonds with many other small atoms, including carbon atoms, and is prevalent in a large number of chemical compounds. XPS data Table S1 shows the atomic concentration of all species calculated from their measured peak areas. Deconvolution results of XPS spectra of SP800 carbon. Four allotropes of carbon are known: amorphous (e.g., charcoal and soot), graphite, diamond, and fullerenes. High-resolution X-ray photoelectron spectra (C1s, O1s and P2p core level) of carbon SP800. from publication: Identifying Site-Dependent Reactivity in Oxidation Reactions on Single Pt Particles Catalytic nanoparticles are.

observed in their CN x:H films a C1s XPS peak at 287.5 eV, by 3.1 eV above the binding energy of the C C bonds in graphite. Download Table Analysis of the C1s and N1s XPS peak area. Obtained from: burning with insufficient oxygenĬarbon has been known since ancient times when it was produced by burning organic material in the presence of insufficient oxygen. , deconvoluted the C1s XPS peak into five components at approximately 284.7, 285.3, 286.7, 287.7 and 289.6 eV which were assigned to pure carbon, C N, C N, C N, and C O bonds, respectively.
