aluminum formate

Exhaust from coal-fired power plants, at left, contains large quantities of the greenhouse gas carbon dioxide (purple tripartite molecules). Aluminum formate, a metal-organic framework whose structure is highlighted at right, can selectively capture carbon dioxide from dried flue gas conditions, potentially at a fraction of the cost of using other carbon filtration materials.
