Significance A novel approach for ultra‐deep desulfurization of diesel fuel was proposed, in which the original fuel was treated by light irradiation before adsorptive desulfurization (ADS) over the TiO 2 –CeO 2 /MCM‐48 adsorbent under ambient conditions. A superior capacity of 95 cm 3 ‐fuel/g‐adsorbent (32 times higher than that of the original fuel) was achieved. The promoting effect of light irradiation was likely through in situ peroxides generation in fuel under visible light/sunlight, which may oxidize organosulfur to form strongly adsorbed sulfones over the adsorbent.
