The advancement of renewable energy critically depends on the rational design of catalysts, which necessitates a thorough understanding of the underlying materials. At Shanghai Synchrotron Radiation Facility (SSRF), the Energy Material beamline (E-line) has been established with three independent endstations - soft X-ray, hard X-ray and a combined soft/hard station - dedicated to fundamental studies of photovoltaic and catalytic processes, energy conversion mechanisms and related phenomena. Covering a broad photon energy range from 130 eV to 10000 eV, the combined endstation is specifically designed for in situ photoemission spectroscopy, enabling layer-by-layer analysis of materials and devices. Through techniques such as wide-range hard X-ray photoemission spectroscopy (HAXPES) and X-ray absorption spectroscopy (XAS), this endstation provides comprehensive insights into the chemical and electronic properties of catalysts. This report outlines the layout of the combined soft/hard beamline and the endstation, and evaluates its performance in terms of photon flux, energy resolution and representative applications in model catalysis. In particular, the use of in situ X-ray photoemission spectroscopy/HAXPES is expected to significantly advance the fundamental understanding of functional materials, thereby accelerating the development of efficient, reliable and affordable renewable energy solutions.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
