Boron nitride nanosheets (BNNS) were used to anchor bimetallic Pd-Fe nanoparticles for Suzuki-Miyaura coupling catalysts. The bimetallic nanoparticles were found to be core-shell in structure, and their formation was likely facilitated by their interactions with the BNNS. The Pd-Fe/BNNS catalysts were highly effective in representative Suzuki-Miyaura reactions, with performances matching or exceeding those of the state-of-the-art methods. Specifically, the superior catalytic activities were characterized by generally shortened reaction times, minimal Pd usage, excellent reusability of the catalysts and high or nearly quantitative conversion yields in a benign solvent system without the need for any special conditions, such as ligands and surfactants or inert gas protection. The obvious advantages of the Pd-Fe/BNNS over similar catalysts based on other supports, such as reduced graphene oxide (rGO), suggest that BNNS may be developed into a versatile platform for many other important catalytic reactions.
氮化硼纳米片 (BNNS) 被用于固定双金属 Pd-Fe 纳米粒子作为 Suzuki-Miyaura 偶联催化剂。发现这些双金属纳米粒子具有核壳结构，它们的形成可能是由于与 BNNS 的相互作用而促成的。Pd-Fe/BNNS 催化剂在代表性的 Suzuki-Miyaura 反应中非常有效，其性能与最先进的方法相匹配或超过。具体而言，优越的催化活性表现为通常缩短反应时间、最小化 Pd 的使用量、催化剂的出色可重复使用性以及在无需任何特殊条件（例如配体和表面活性剂或惰性气体保护）的良性溶剂体系中实现高或近乎定量的转化率。与基于其他载体（如还原氧化石墨烯 (rGO)）的类似催化剂相比，Pd-Fe/BNNS 的明显优势表明，BNNS 可能被开发为许多其他重要催化反应的通用平台。
