Eight halogen-free deep eutectic solvents (DESs) with low viscosity were synthesized for the capture and subsequent catalytic conversion of SO2. The resulting DESs exhibit excellent SO2 solubility (up to 1.2514 g g-1 at 20 °C and 1 bar) and high catalytic activity in the cycloaddition between SO2 and epoxides. Spectroscopic and theoretical investigations elucidate the mechanisms of SO2 capture and conversion, revealing a synergistic effect between hydrogen bond donors (HBDs) and hydrogen bond acceptors (HBAs).
