Focus of the figure: This review summarizes the use of ionic liquids in oxidative desulfurization, comparing acidic, polyoxometalate, supported, and magnetic systems. It discusses reaction mechanisms, catalytic performance, stability, and industrial potential, highlighting task‐specific ILs for efficient deep desulfurization under mild, green conditions. More information about this picture will be discussed by Dr. Bing Hu and his co‐workers on page 274‐301 in this issue. image
