Deep Eutectic Solvents Formed by Complex Hydrides: A New Class of Hydrogen‐Rich Liquid

Andreas Züttel, Thi Ha My Pham, Loris Giovanni Lombardo

Deep eutectic solvents (DESs) are novel mixtures that exhibit a significant depression in melting points compared to their individual components. This work finds that combining tetrabutylammonium borohydride (TBABH) with ammonia borane (AB) yields new, sta ...

Direct CO2 Capture and Reduction to High-End Chemicals with Tetraalkylammonium Borohydrides

Andreas Züttel, Loris Giovanni Lombardo, Kun Zhao, Heena Yang, Youngdon Ko

We demonstrate the ability of tetraalkylammonium borohydrides to capture large amounts of CO2, even at low CO2 concentrations, and reduce it to formate under ambient conditions. These materials show CO2 absorption capacities up to 30 mmolCO2 g(-1) at room ...
