Abstract

The basis of X-ray photoemission spectroscopy (XPS) will be briefly addressed and, as practical examples, we will show many applications on carbon-based materials obtained using synchrotron radiation in real-time. The carbon nanostructures (CNs) were grown via catalytic chemical vapour deposition and were investigated using complementary spectroscopic and microscopy techniques, also in situ and during the synthesis process. In addition to XPS, the CNs were investigated using scanning microscopies, high resolution transmission electron microscopy, and low energy electron diffraction. Flux, energy and lateral resolution available using synchrotron radiation are extremely high. These unique characteristics enable the identification of some of the key growth mechanisms and help to identify the best catalyst condition to control the growth process and the final CNs.
