Improvement of Hydrogen Storage with Nanomaterials

Hydrogen is the most promising fuel for the next generation energy applications. It is preferred due to it is very clean and efficient. However, hydrogen in its gas state is very dangerous especially in transportation application. The integration of the nanotechnology in the field of the hydrogen storage and transport is showing fabulous results. These results can be achieved by the preparation of the nanoparticles that have the high capacity for the hydrogen storage or the ability to extract hydrogen from the stable and safe chemicals that can be used. Few materials can act like a sponge for the absorption and release of hydrogen, these materials are the best choice for hydrogen storage systems. Some of the critical issues that faces such systems are the amount of hydrogen that can be stored in such materials and how fast can the hydrogen be stored and released.

Nanomaterials with such properties show high potential for high quantity storage and fast adsorption and release of the hydrogen. Nanomaterials such as, nanoparticles, nanotubes, nanocomposite, and nanofibers are used and studied for these applications. Continuous research for the synthesis and the characterization of new nanomaterials is conducted for the improvement of the existing materials and the introduction of new ones that may have extraordinary properties.
The most important property of these nanomaterials is the high surface area and volume to mass ratio. This enables them to interact with more hydrogen atoms and to have ability to store mare of them. Moreover, it allows them to have more space in the bottom which speed up the adsorption and the release process. Some examples of these materials are lithium nitride, platinum nanoparticles, borohydrides nanoparticles, carbonaceous nanomaterials such as graphene and nanotubes.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from: https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread that i

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs) have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product.
