X-ray photoelectron spectroscopy (XPS) and reflection electron energy loss spectroscopy (REELS) were employed to characterize the electronic properties of Prussian blue (PB) and its analogs when electrodeposited over metal-decorated carbon nanotubes (CNTs). Through an investigation of the influence of carbon nanotubes (CNTs) and preparation conditions on the electronic structure, valuable insights were obtained regarding their effects on electrochemical properties. XPS analysis enabled the probing of the chemical composition and oxidation states of the film materials, unveiling synthesis-driven variations in their electronic properties. REELS provided information on energy loss and electronic transitions, enabling further characterization of the changes in the electronic structure induced by different preparation methods. Such findings emphasize the importance of surface characterization to understand how the unique electronic properties of such materials can be harnessed to enhance their performance and functionality.
采用X射线光电子能谱（XPS）和反射电子能量损失谱（REELS）来表征普鲁士蓝（PB）及其类似物在金属修饰的碳纳米管（CNT）上电沉积时的电子性质。通过研究碳纳米管（CNT）和制备条件对电子结构的影响，获得了关于它们对电化学性质影响的有价值见解。XPS分析能够探测薄膜材料的化学成分和氧化态，揭示了合成驱动的电子性质变化。REELS提供了关于能量损失和电子跃迁的信息，能够进一步表征不同制备方法引起的电子结构变化。这些发现强调了表面表征对于理解如何利用此类材料独特的电子性质来提高其性能和功能的重要性。
