Noble metal nanoclusters are unique materials given their unexpected structure-property relationships. To elucidate the properties of metal nanoclusters, synchrotron-based X-ray spectroscopy techniques can provide valuable information from an element-specific perspective. In particular, X-ray absorption spectroscopy (XAS) can provide structural details on the bond length and coordination number of various neighboring atoms while X-ray photoelectron spectroscopy (XPS) mainly offers electronic structure information. Together, XAS and XPS can reveal important findings on the properties of metal nanoclusters from both the protecting ligand and different metal atom environments. This work will demonstrate the usefulness of synchrotron-based X-ray spectroscopy techniques, along with complimentary methods, towards an understanding of metal nanocluster structure and properties. X-ray meausrements in various experimental conditions such as liquid-phase, low temperature, and time-dependent are easily performed, which lends to the diversity of our X-ray studies on metal nanocluster systems.
