Nowadays, the scientific community is actively researching the advancement of a sustainable effective desulfurization technique. The development of alternative or supplementary approaches to desulfurization has rapidly progressed in recent years. Among these approaches, the oxidative desulfurization (ODS) process stands out as a highly promising method. This can be attributed to its notable selectivity, cost-effectiveness, mild reaction conditions, and overall efficiency. It is essential to consider the role of oxidants, catalysts, and operating conditions in optimizing the ODS process. This review examines a comprehensive understanding of the ODS process and its potential applications in desulfurization. It highlights the importance of oxidants, extractant solvent, and other operating conditions in the ODS process and discusses the different groups of catalysts that can be used. In addition, the review examines five distinct groups of heterogeneous catalysts used in the ODS process: transition metal oxides stabilized, polyoxometalates, ionic liquids, carbon materials, and porous materials. The role of ionic liquids in catalytic and extractive oxidation is also explored. In recent years, alternative or supplementary desulfurization methods have been rapidly developed. The review discusses the advantages and disadvantages of each approach. It explores various techniques that can be employed to mitigate the drawbacks associated with each system.

“…To solve the above problems, non-HDS technologies have been developed, such as adsorptive desulfurization (ADS) [5][6][7][8], extractive desulfurization (EDS) [9][10][11][12], oxidative desulfurization (ODS) [13][14][15], and biodesulfurization (BDS) [16,17]. Among them, ODS integrated with adsorption/extraction is receiving increasing attention, due to its nonhydrogen consumption, enhanced efficiency, mild reaction conditions, low cost, stronger operability, and practicability [18][19][20][21].…”

Oxidative desulfurization (ODS) has attracted much attention owing to the mild working conditions and effective removal of the aromatic sulfur-containing compounds which are difficult to desulfurize using the industrial hydrodesulfurization (HDS) technique. Molecular oxygen in ambient air have been recognized as an ideal oxidant in ODS due to its easy availability, non-toxicity and low cost in recent years. However, molecular oxygen activation under mild operating conditions is still a challenge. Porous materials and their composites have drawn increasing attention due to their advantages, such as high surface area and confined pore space, along with their stability. These merits contribute to the fast diffusion of oxygen molecules and the formation of more exposed active sites, which make them ideal catalysts for aerobic oxidation reactions. The confined space pore size offers a means of catalytic activity and durability improvement. This gives rise to copious attention toward the porous catalysts in AODS. In this review, the progress in the characteristics and AODS catalytic activities of porous catalysts is summarized. Then, emphasis on the molecular oxygen activation mechanism is traced. Finally, the breakthroughs and challenges of various categories of porous catalysts are concluded.

“…Some desulfurization methods also show especially fast and efficient desulfurization performance under mild operating conditions. [20][21][22][23] A deep eutectic solvent (DES), first proposed by the Abbott group, usually consists of two or more compounds containing hydrogen bond donors (polyols, carboxylic acids, amides, etc.) and hydrogen bond receptors (quaternary ammonium salts, quaternary phosphonium salt, etc.).…”
