Abstract In this paper, a novel Ni 2 P/black phosphorus (Ni 2 P/BP) supported on two‐dimensional α‐zirconium phosphate (α‐ZrP) hybrid material was prepared, and its catalytic activity for hydrodesulfurization (HDS) was investigated. Through the reaction of nickel salt with BP nanosheets obtained by freeze‐assisted exfoliation method, Ni 2 P nanoparticles can be formed and firmly anchored on the surface of BP, effectively preventing themselves from aggregating. BP is not only used as the phosphorus source for the synthesis of Ni 2 P, but its superior electron mobility can significantly promote the catalytic HDS activity of Ni 2 P species. Moreover, the support of two‐dimensional α‐ZrP nanosheets with a large specific surface area has a strong structure, which greatly improves the stability of catalyst. The Ni 2 P/BP@ZrP catalyst could reach a dibenzothiophene (DBT) conversion of 87.4 % within 6 h at 260 °C, much higher than the traditional NiMo/Al 2 O 3 catalyst (65.6 %), showing a promising application for industrial catalytic desulfurization.
