The surface of a material plays a vital role in the overall properties of the material, especially the optical/electrical/magnetic properties of the material, which are mainly determined by the surface properties of the material. In particular, several important new disciplines since the 21st century, such as nanoscience, microelectronics, catalysis and energy materials, are ultimately about studying the surface properties of materials. Therefore, the role of surface analysis in physical/chemica

The main function of catalytic materials comes from the surface of the materials, so studying the reaction characteristics of the material surface with different media can help us understand the characteristics of catalytic materials from one aspect. However, traditional research methods cannot achieve in-situ or quasi-in-situ research methods. Samples will inevitably be contaminated by air/tools or even operators during the transmission process, and the properties of catalytic materials will

Synchrotron radiation is electromagnetic radiation emitted by charged particles with a speed close to the speed of light (v≈c) moving along an arc track in a magnetic field. Since it was first observed on a synchrotron, it is also called "synchrotron radiation" or "synchrotron radiation". Synchrotron radiation is a pulsed light source with excellent properties such as continuous spectrum from far infrared to X-ray, high intensity, high collimation, high polarization, and precise control of chara
