2. In-situ / Operando X-ray Techniques Analysis
Yu-Chang Lin is an Assistant Research Scientist in the X-ray Absorption Group at the National Synchrotron Radiation Research Center (NSRRC), Taiwan, since 2024. He received his Ph.D. in Materials Science and Engineering from National Yang Ming Chiao Tung University in 2021. His research focuses on photocatalytic and electrocatalytic materials, with an emphasis on in situ and operando approaches. He uses X-ray spectroscopy techniques, including X-ray absorption spectroscopy (XAS) and X-ray emission spectroscopy (XES), to investigate dynamic processes and structure–property relationships in energy-related materials. He is also involved in the construction and future operation of the TPS 38A X-ray Absorption Spectroscopy beamline.

Applications of Synchrotron Radiation in Catalysis/TBA
As a cornerstone of the Taiwan Photon Source (TPS) Phase III development, the TPS 38A beamline serves as a cutting-edge experimental hub designed to push the frontiers of X-ray spectroscopy. By integrating an advanced suite of techniques—including Quick-scanning X-ray Absorption Spectroscopy (QXAS), X-ray Absorption Fine Structure (XAFS), and X-ray Emission Spectroscopy (XES)—this facility provides an unprecedented platform for deciphering the complex interplay between atomic structures and electronic states in functional materials.
A primary highlight of the beamline’s capability is its application in electrocatalysis, specifically the Oxygen Evolution Reaction (OER). Given that OER is often the efficiency-limiting step in water splitting due to its sluggish kinetics and multi-electron transfer nature, the high-temporal resolution of QXAS at TPS 38A enables researchers to capture transient intermediates and identify active sites under operando conditions. Furthermore, the implementation of Kβ X-ray Emission Spectroscopy provides a direct probe into the 3d spin-state transitions (high-spin vs. low-spin) of transition metal centers. By correlating these electronic configurations with the local geometric evolutions revealed by XAS, a holistic map of the reaction mechanism can be constructed.
The synergy of these advanced spectroscopic tools at TPS 38A empowers the scientific community to transition from descriptive observation to the rational, theory-backed design of highly efficient and stable materials for energy and environmental engineering. Looking forward, TPS 38A remains committed to pioneering ultra-fast, time-resolved, and multi-technique integration to drive the next wave of innovation in interdisciplinary material research.
