This project aims to develop new porous hydrogen storage materials which utilize molecular chemisorption of hydrogen rather than mere physisorption, and ultimately do this in low weight hybrid materials. Stronger binding of hydrogen should result in greater capacity and lower operating pressures at room temperature. These studies should lead to the design and synthesis of hydrogen storage mater...

The effects of different temperatures on the hydrogen sorption characteristics of double-walled carbon nanotubes (DWCNTs) with palladium loading have been investigated. When we use different temperatures, the particle sizes and specific surface areas of the samples are different, which affects the hydrogen storage capacity of the DWCNTs. In this work, the amount of hydrogen storage capacity was...

The newly found B40 is the first experimentally observed all-boron fullerene and has potential applications in hydrogen storage. Here we investigate the binding ability and hydrogen storage capacity of Ti-decorated B40 fullerene based on DFT calculations. Our results indicate that Ti shows excellent binding capability to B40 compared with other transition metals. The B40 fullerene coated by 6 T...

Based on recently published papers, this article introduces the characteristics, hydrogen storage capacity, and economic advantages of the adsorptive carbon system, zeolite, and glass microspheres as possible methods of hydrogen storage. The adsorbents for hydrogen storage now available on the market are activated carbon and zeolite. In terms of hydrogen adsorption, zeolite can adsorb 1 wt perc...

In this study, doped vanadium oxide nanotubes were evaluated using different software to study the absorption of hydrogen gas. Vanadium oxide nanotubes are one of the options for absorption and storage hydrogen gas. In this research study for the first time, the Monte Carlo simulation was used to investigate the hydrogen gas absorption behavior in molybdenum-tungsten, molybdenum-zirconium and z...

The Electrochemical Society Interface • Fall 2004 ydrogen storage is a crucial step for providing a ready supply of hydrogen fuel to an end use, such as a car, as it is considered by many to be the most technically challenging aspect of achieving a hydrogen-based economy. Current hydrogen storage materials or systems are still far short of meeting target goals set for either 2010 or 2015. Two k...

In order to increase gas storage capacity such as hydrogen and methane, various wt% of cobalt were decorated on the surface of MWCNTs which was already treated nitric and sulfuric acids to provide functional groups on the surface of MWCNTs. The characteristic peak of SO4 in FT-IR spectrum was at 1220 cm, which was resulting from sulfuric acid treatment. This peak implies that acid treatment con...
