Abstract
En 中文
Approximately 40 yr have passed since X-ray synchrotron radiation (SR) first became available in Japan. SR has opened a new spectroscopic field called X-ray absorption fine structure (XAFS). In 2024, a new Fourth-generation SR facility, NanoTerasu, was opened in Sendai. On this occasion, I would like to give my personal review of 40 yr of development of XAFS in Japan, especially its applications in catalyst research, and discuss its future. Since 1982 when Photon Factory was launched, synchrotron X-ray radiation has enabled major advances in X-ray absorption fine structure (XAFS) research in Japan. This technique has played an important role in understanding catalysts by revealing how atoms behave during chemical reactions. With the opening of the new synchrotron facility NanoTerasu in 2024, this article looks back on the development of XAFS in Japan and considers its future contributions to science and society.
