Synchrotron X-ray spectroscopy techniques such as X-ray absorption spectroscopy are useful tools for the element-specific analysis of structural and bonding properties of materials. In this contribution, the application of these techniques in the study of some nanometallic systems will be presented. Materials of particular interest include noble metal nanoclusters, shape-controlled nanocrystals and nanocluster-nanocrystal hybrid systems. It will be demonstrated that the X-ray spectroscopy methods, in association with complementary techniques and quantum simulations, can sensitively probe the structural and property changes induced by the effects such as nanocluster composition, protecting ligands, nanocrystal shape and alloy bonding. The structural information revealed by the X-ray techniques may also be useful in guiding the catalytic and biomedical applications of these materials.
