Abstract

Hydrogen is a promising energy carrier. Coupling hydrogen production to renewable energy sources would help alleviate the world's dependence on fossil fuels. A hurdle that must be overcome for that scenario is the development of satisfactory hydrogen storage media. Theoretical work suggests that carbon-based nanomaterials are plausible candidates; The research objective of this work is to study the influence of hydrogen adsorption on the chemical and electronic properties of carbon-based nanomaterials (i.e., single-walled carbon nanotubes and C60). An atomic hydrogen source was constructed. Nanomaterials were exposed to atomic and/or molecular hydrogen, and the local chemical and electronic interaction was studied using Photoelectron Spectroscopy. Annealing of hydrogenated samples shows the reversibility of the adsorption of atomic hydrogen. The results obtained give detailed information about hydrogenation-induced chemical and electronic interactions, showing that Photoelectron Spectroscopy, with the atomic hydrogen source, is a powerful tool to investigate the hydrogen storage potential of carbon-based nanomaterials.
