New Material Captures Carbon at Half the Energy Cost

The diamine-appended metal-organic framework before and after binding of carbon dioxide. The view is a cross section through one of the pores of the MOF, showing diamine molecules (containing blue nitrogen atoms) attached to metal (manganese) atoms (green). Carbon dioxide molecules (grey carbon atoms with two red oxygen atoms) bind through a cooperative mechanism akin to a chain reaction along the pore surfaces. Some H atoms (white) are omitted for clarity. (Credit: Graphic by Thomas McDonald, Jarad Mason, Jeffrey Long/UC B) Click to Enlarge.
Capturing carbon from power plants will likely be necessary in the future to avoid the worst effects of climate change, but current technologies are very expensive.  Chemists have now developed a new material, a diamine-appended metal-organic framework, that captures carbon dioxide with much reduced energy costs compared to today's technologies, potentially lowering the cost of capturing and sequestering this greenhouse gas.
