We studied the x-ray absorption fme structure (EXAFS) of Ru-C60 and Ru in fullerene black employing the K-edge of rutheniumn. The EXAFS analysis of the local structure in both systems allows the observation of small metallic particles and their modification caused by the effect of temperature and/or the usage of the samples as catalyst.
