MOF captures carbon dioxide at high-temperatures (IMAGE)
Caption
At center left is one of the crystalline building blocks of a thermally stable metal-organic framework (MOF), known as ZnH-MFU-4l, that is able to reversibly and selectively capture the greenhouse gas carbon dioxide from a mix of many industrially relevant gases. CO2 is highlighted at left, among nitrogen, oxygen, hydrogen, carbon monoxide and water molecules. The MOF can capture CO2 over many cycles at 300 C, which is a typical temperature of the exhaust streams from cement and steel plants. The zinc hydride groups in the MOF reversibly bind and release the carbon dioxide molecules (right). Light-blue, gray, blue, red, and white spheres represent Zn, C, N, O, and H atoms, respectively.
