Palladium is well known to show high performance as the hydrogen storage materials. We have used the X-ray absorption fine structure (XAFS) technique with dispersive optics mode in order to understand the size effect of the Pd nanoparticles concerning the hydrogen storage process from the viewpoint of the dynamical change of atomic and electronic structures during the reaction between Pd particles and hydrogen gases. It is recognized that the high speed chemical reaction between Pd nanoparticles and hydrogen gases was finely observed by high speed XAFS observation rate at 200 Hz.
