Abstract

The atomic-level interfacial regulation of single metal sites through heteroatom doping can significantly improve the characteristics of the catalyst and obtain surprising activity. Herein, nickel single-site catalysts (SSCs) with dual-coordinated phosphorus and nitrogen atoms were developed and confirmed (denoted as Ni-P_xN_y, x = 1, 2 and y = 3, 2). In CO₂ reduction reaction (CO₂RR), the CO current density on Ni-P_xN_y was significantly higher than that of Ni-N₄ catalyst without phosphorus modification. Besides, Ni-P₁N₃ performed the highest CO Faradaic efficiency (FE_CO) of 85.0%–98.0% over a wide potential range of −0.65 to −0.95 V (vs. the reversible hydrogen electrode (RHE)). Experimental and theoretical results revealed that the asymmetric Ni-P₁N₃ site was beneficial to CO₂ intermediate adsorption/desorption, thereby accelerating the reaction kinetics and boosting CO₂RR activity. This work provides an effective method for preparing well-defined dual-coordinated SSCs to improve catalytic performance, targetting to CO₂RR applications. [Figure not available: see fulltext.]
