摘要：Phosphorus (P) doped NiS₂ with abundant sulfur (S) vacancy, denoted as Svac-P-NiS₂ is synthesized and investigated as a bifunctional electrocatalyst for benzyl alcohol (BA) oxidation and hydrogen evolution reaction (HER). The high valence Ni lowers the energy barrier. Meanwhile, the S vacancy contributes to the activation of C-H bonds. The dopant and vacancy exhibit the indispensable synergistic effect in the electrocatalytic process, which greatly promotes the electrocatalytic performance of Svac-P-NiS₂.
