Fuel desulfurization is of utmost importance to mitigate multiple environmental issues. Ionic liquids with unique adjustable properties have emerged as highly promising solvents for fuel extractants. Nevertheless, it remains challenging rationally design ionic in view the extraction mechanism. This review comprehensively discusses recent progress research on extractive desulfurization. The commonly adopted methods explore mechanism are summarized, including characterization and computational methods. In terms different functional groups, classified into six categories, imidazolium-, metal-, amino or phosphonium-, polyether glycol-, pyridinium-based, protic liquids. According mechanisms discussed detail, emphasis placed role dominant interactions sulfur-containing compounds, π···π, S–M complexation, C–H···π, hydrogen bonding. aims provide a theoretical foundation designing functionalized by summarizing More importantly, will guidance utilizing targeted
