Hydrogen storage is one of the most addressed issues in the green-economy field. The latest-discovered form of ice (XVII), obtained by application of an annealing treatment to a H2-filled ice sample in the C0-phase, could be inserted in the energy-storage context due to its surprising capacity of hydrogen physisorption, when exposed to even modest pressure (few mbars at temperature below 40 K),...

The hydrogen storage mechanism of SWNTs was studied through molecular dynamics simulations. Assuming the simple physical adsorption of hydrogen to the surface of SWNTs, potential forms between H2-H2 and C-H2 were both expressed by Lennard-Jones functions. Fixing the relative coordinates of carbon atoms to the center of mass of each SWNT, the center of mass motion was modeled with the van der Wa...

A safe and efficient method for storing hydrogen is solid state storage through a chemical reaction in metal hydrides. A good amount of research has been conducted on hydrogenation properties of metal hydrides and possible methods to improve them. Background research shows that heat transfer is one of the reaction rate controlling parameters in a metal hydride hydrogen storage system. Consideri...

Hydrogen spillover and storage for single-site metal catalysts, including single-atom catalysts (SACs) single nanocluster have been elucidated various supports but remain poorly understood inert carbon supports. Here, we use synchrotron radiation-based methods to investigate the role of Ti on graphene hydrogen storage. Our in-situ angle-resolved photoemission spectra results demonstrate a bandg...

Hybrid nanotubes of carbon and halloysite nanotubes (HNTs) with different carbon:HNTs ratio were hydrothermally synthesized from natural halloysite and sucrose. The samples display uniformly cylindrical hollow tubular structure with different morphologies. These hybrid nanotubes were concluded to be promising medium for physisorption-based hydrogen storage. The hydrogen adsorption capacity of p...

Hydrogen Storage Materials In article number 2300041, Yong-Hoon Kim, Jeung Ku Kang, and co-workers describe hydrogen storage materials achieved by amorphized defective fullerene with single-atom platinum. via spillover enables high reversible gravimetric (6.8 wt.%) volumetric (64.9 kg m−3) capacities, hitherto the highest capacities close to US Department of Energy targets at room temperature, ...

The search for new materials for hydrogen storage is important for the development of future hydrogen energy applications. In this Thesis, it is shown that new materials with interesting properties can be synthesized by the reaction of hydrogen with various nanocarbon precursors. The thesis consists of two parts. The first part is devoted to studies of hydrogen storage in some metalorganic fram...
