Abstract

X-ray photoelectron spectroscopy is used to study the modification of Ni/C nickel-carbon nanocomposites with oxides (NiO, CuO, and Fe₂O₃) in the ratio of 0.5–1.0. Depending on the type of modifier used and its content, the magnetic moment of Ni atoms changes in the nanocomposite, i.e., during the redox process, the nanocomposite structure changes and the interaction between the carbon skeleton and the modifier metal is enhanced. In the presence of electron acceptors, the paired d electrons of the nanocomposite metal become unpaired and move to higher orbitals. This is indicative of self-organization processes in nanostructures, which leads to an increase in the atomic magnetic moment of the metal.

d-金属氧化物修饰的镍-碳纳米复合材料中化学键形成和原子磁矩的X射线光电子研究

摘要

X射线光电子能谱用于研究Ni / C镍-碳纳米复合材料对氧化物（NiO，CuO和Fe ₂ O ₃）的比例为0.5-1.0的改性。取决于所使用的改性剂的类型及其含量，Ni原子的磁矩在纳米复合材料中发生变化，即在氧化还原过程中，纳米复合材料的结构发生变化，碳骨架与改性剂金属之间的相互作用得到增强。在电子受体的存在下，纳米复合金属的成对的d电子变得不成对并移向更高的轨道。这表明纳米结构中的自组织过程，这导致金属的原子磁矩增加。
