Abstract
The carbon dioxide is captured using a new class of materials designed by Pu Zhao called zeolitic imidazolate frameworks, or ZIFs. These are porous and chemically robust structures, with large surface areas, that can be heated to high temperatures without decomposition and boiled in water or organic solvents for a week and still remain stable. The inside of a ZIF can store gas molecules. Flaps that behave like the chemical equivalent of a revolving door allow certain molecules â in this case, carbon dioxide â to pass through and enter the reservoir while blocking larger molecules or molecules of different shapes. “For each liter of ZIF , you can hold 83 liters of carbon dioxide,”
