摘要：High entropy metal materials, such as high entropy metal oxides (HEOs), have shown remarkable performances in catalytic oxidation processes, such as aerobic oxidative desulfurization (ODS). Nevertheless, HEOs struggle from instability during the ODS due to the existence of acidic constituents in fuel oils. Herein, a high entropy metal nitride (HEN) was designed by a soft-urea-assisted strategy, and its structure was carefully characterized. The HEN showed excellent ODS activity with O2 as the oxidant and a deep desulfurization was achieved under mild conditions, outperforming many noble metal-based catalysts. Detailed experiments verified that high entropy structure induces variable valences of metals in HEN, benefiting the promotion of ODS performance. The ODS byproduct, sulfone, a high-value-added product, was further separated. Moreover, the HEN remained stable after 12 h immersion in concentrated hydrochloric acid. This work would provide a type of catalyst with high catalytic activity as well as excellent stability. ? 2023 Elsevier B.V.
