Porous networks of organic Van der Waals crystals can selectively store methane and carbon dioxide
Washing powders are generally known to consist partially of inorganic zeolites. These aluminosilicates form porous structures whose cavities can act as storage for ions and molecules. In washing powders, they bind the calcium and magnesium ions that cause water to be hard. Largely unknown, however, are organic zeolites, which are also highly promising for applications such as the storage, separation, and purification of gases.
