Functionalized ionic liquids, such as amino, carboxyl, and hydroxyl groups, can be efficiently used to capture and convert carbon dioxide.
Functional ionic liquids are formed by introducing functional groups into traditional ionic liquids. They have both good absorption capacity and excellent catalytic activity for carbon dioxide, and therefore are widely used in the chemical conversion of carbon dioxide. This paper focuses on the application of amino-functionalized ionic liquids, carboxyl-functionalized ionic liquids, hydroxyl-functionalized ionic liquids and various other functionalized ionic liquids in carbon dioxide conversion. Their possible role in chemical carbon fixation is discussed by analyzing several typical chemical carbon fixation mechanisms.Zum Volltext
