TI  - Designing Inorganic-Organic Dual-Acid Deep Eutectic Solvents for Synergistically 
      Enhanced Extractive and Oxidative Desulfurization.

AB  - Acidic deep eutectic solvents (DESs) have been considered desirable extractants 
      and catalysts for desulfurization. However, their hydrogen bond donors (HBDs) are 
      usually sole organic acids, which are not conducive to efficient green catalysis. 
      Herein, a novel inorganic-organic dual-acid DES (DADES) was reported for 
      efficient extractive and oxidative desulfurization. Benefiting from the physical 
      interaction among the three components in a DADES, a transparent homogeneous 
      liquid can be obtained even though inorganic acid (boric acid, BA) and organic 
      acid (acetic acid, AA) can be immiscible. Furthermore, the dual-acid HBD can 
      increase the acidity of the DADES and reduce its viscosity, accelerating its mass 
      transfer efficiency and enhancing its catalytic activity. With 
      1-butyl-3-methylimidazolium chloride ([Bmim]Cl) as the hydrogen bond acceptor, 
      [Bmim]Cl/BA/0.3AA effectively activated hydrogen peroxide and achieved sulfur 
      removal of 96.6% at 40  degrees C. Furthermore, the universality of the synergistic 
      effect in various DADESs was confirmed by the modulation of the types of organic 
      acids. This study not only motivates the construction of more intriguing novel 
      DESs based on the DADES concept but also highlights their potential in clean fuel 
      production.
