ABSTRACT Binary metal oxides hold immense potential in catalysis; however, their efficient utilization remains a significant challenge. Zinc tungstate (ZnWO 4 ) was loaded onto graphitic carbon nitride (g‐C 3 N via highly and energy‐saving room‐temperature stirring method to prepare ZnWO /g‐C (ZnWO/CN) composite with sandwich structure for oxidative desulfurization. The appearance, structure, stability of ZnWO/CN were characterized by X‐ray diffraction (XRD), Fourier transform infrared (FT‐IR) spectroscopy, photoelectron spectroscopy (XPS), some other characterization tests. Results demonstrate the successful incorporation nanoparticles within layered porous g‐C , achieving dispersed state. In addition, exhibits significantly higher specific surface area enhanced compared pure effectively mitigates propensity towards agglomeration. catalytic performance evaluation indicates that (30 wt%) achieves exceptional desulfurization efficiency at lower preparation cost. A near‐complete sulfur removal rate 99.89% achieved 180 min under optimized conditions ( m (catalyst) 20.00 mg, V (ILs)/ (Oil) 1/20, (H 2 O 0.2 mL, 80°C). Furthermore, catalyst retained high even after eight consecutive cycles. Notably, adsorption affinity reactants enabled reduction ionic liquid dosages. By combining testing, quenching experiment, EPR test, reaction mechanism oxidation ultimately obtained. this provides research ideas new supported catalysts.

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