Diesel soot (Euro IV and Euro VI) was investigated with spectroscopic methods such as near-edge X-ray absorption fine structure (NEXAFS) spectroscopy and X-ray photoemission spectroscopy (XPS). C and O K-edge NEXAFS show that structural disorder on the surface is accompanied by a higher amount of oxygen functional groups. O K-edge NEXAFS and O1s XPS results are discussed with the aim to elucidate the nature of the oxygen surface species. The analysis of the data presented here allows the postulation of a hypothetical structure for soot samples emitted by diesel engines.
采用近边 X 射线吸收精细结构（NEXAFS）光谱和 X 射线光电子能谱（XPS）等光谱方法研究了柴油机烟尘（欧 IV 和欧 VI）。C 和 O K 边 NEXAFS 表明，表面结构无序伴随着更多的氧官能团。O K 边 NEXAFS 和 O1s XPS 结果进行了讨论，目的是阐明氧表面物种的性质。对这里呈现的数据的分析允许对柴油机排放的烟尘样品的假设结构进行推测。
