摘要：
This short review deals with some recent XAFS (X-ray absorption. ne structure) applications to catalysts in Japan. The high transmission ability of X rays makes it possible to carry out in situ work on catalysts. First, in situ XAFS works underflow and high-pressure reaction conditions will be described. The time-resolved XAFS work will be another important topic because it can provide the possibility of observing the change of the reaction active site and the reaction intermediate. Finally, PTRF-XAFS will be described, which is a unique technique and provides three-dimensional local structures of highly dispersed surface species.
