Using X‑ray Photoelectron Spectroscopy To Evaluate Size of Metal Nanoparticles in the Model Au/C Samples

The work demonstrates the possibilities to determine the size of gold nanoparticles in the planar model Au/C systems based on the data of XPS using Davis’ method. The size of gold particles was evaluated using the normalized intensity ratio of the Au 4f7/2 and Au 3d3/2 lines excited by high-energy r...

Summary:The work demonstrates the possibilities to determine the size of gold nanoparticles in the planar model Au/C systems based on the data of XPS using Davis’ method. The size of gold particles was evaluated using the normalized intensity ratio of the Au 4f7/2 and Au 3d3/2 lines excited by high-energy radiation Ag Lα ( h ν = 2983.4 eV). STM was used for direct control of the particle sizes. It is shown that the Davis method gives a satisfactory estimation of the size of gold particles deposited on the planar support, and comparison of the XPS and STM data can provide an assumption of the geometric shape of the particles.
