Solvent- and Catalyst-Free Carbon Dioxide Capture and Reduction to Formate with Borohydride Ionic Liquid

The Cover Feature shows the application of a pyrrolidinium-based ionic liquid with a borohydride anion to simultaneously capture and reduce large amounts of CO2. The ionic liquid cation interacts with CO2, allowing the borohydride to fix and reduce it to tri-formatoborohydride (represented as a pitcher plant that can attract and digest CO2). Formic acid can be collected by adding HCl solution. More information can be found in the Full Paper by L. Lombardo et al.
