Characterization of Carbon Materials for Hydrogen Storage and Compression

C, 2020
Carbon materials have proven to be a suitable choice for hydrogen storage and, recently, for hydrogen compression. Their developed textural properties, such as large surface area and high microporosity, are essential features for hydrogen adsorption.

Potentials of physical adsorption

Surface Science Reports, 1991
Abstract A summary of key data concerning physical adsorption potentials is presented. Over 250 gas-surface systems have been considered. For each, we tabulate (when available) the van der Waals adsorption coefficient (C3), the equilibrium distance (zm), well depth (D), and binding energy (Eb) of the laterally averaged interaction potential as ...

Adsorption of polymers on a fluctuating surface

, 1994
We study the adsorption of polymer chains on a fluctuating surface. Physical examples are provided by polymer adsorption at the rough interface between two non-miscible liquids, or on a membrane.

Zeolite phi: a physical mixture of chabazite and offretite [PDF]

, 1992
Zeolite Phi is synthesized by two methods reported previously. Results from X-ray powder diffraction and scanning electron microscopy suggest that the materials are physical mixtures of chabazite and offretite; one sample has a small amount of ...

Photoswitchable Conductive Metal–Organic Frameworks

Advanced Functional Materials, EarlyView.
A conductive material where the conductivity can be modulated remotely by irradiation with light is presented. It is based on films of conductive metal–organic framework type Cu3(HHTP)2 with embedded photochromic molecules such as azobenzene, diarylethene, spiropyran, and hexaarylbiimidazole in the pores.

EFECTO DEL MOF ZIF-8 EN LA FORMACIÓN DE HIDRATOS DE METANO APLICANDO DINÁMICA MOLECULAR

Avances en Ciencias e Ingeniería
The formation of gas hydrates near porous materials is believed to have two main advantages, the porous surface increases the contact between water and gas increasing the conversion of gas to hydrate or the surface chemistry can induce faster hydrate ...

Adsorption of H₂ on Penta-Octa-Penta Graphene: Grand Canonical Monte Carlo Study

C, 2020
In this paper, we report the results of hydrogen adsorption properties of a new 2D carbon-based material, consisting of pentagons and octagons (Penta-Octa-Penta-graphene or POP-graphene), based on the Grand-Canonical Monte Carlo simulations.

First-principles extrapolation method for accurate CO adsorption energies on metal surfaces

, 2004
We show that a simple first-principles correction based on the difference between the singlet-triplet CO excitation energy values obtained by DFT and high-level quantum chemistry methods yields accurate CO adsorption properties on a variety of metal ...

Behaviours of natural organic matter in membrane filtration for surface water treatment : a review [PDF]

, 2006
Membrane application in surface water treatment provides many advantages over conventional treatment. However, this effort is hampered by the fouling issue, which restricts its widespread application due to increases in hydraulic resistances, operational

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

Advanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.
