Gas Storage in Nanoporous Materials

Crystal gas tank. ‘A van der Waals crystal studied by X-ray diffraction could act as a gas storage material for greenhouse gases methane and carbon dioxide. A van der Waals crystal studied by X-ray diffraction could act as a gas storage material for greenhouse gases methane and carbon dioxide, according to researchers in Italy.
The organic counterparts of the aluminosilicate zeolites commonly used as molecular sieves, catalysts, and as water softeners in laundry detergents, are showing promise in small molecule storage, separation, and gas purification, according to Piero Sozzani and his colleagues at the University of Milan-Bicocca. The researchers have now confirmed the properties of crystals of the organic compound tris-o-phenylene-dioxycyclotriphosphazine, which contain a nanoporous network held together, not by the ionic bonds of inorganic salts, but by weaker van der Waals forces.’
