We report a facile method for assembly of a monolayer array of nitrogen-doped graphene (NG) and nanoparticles (NPs) and the subsequent transfer of two layers onto a solid substrate (S). Using 3 nm NiPd NPs as an example, we demonstrate that NiPd-NG-Si (Si=silicon wafer) can function as a catalyst and show maximum NiPd catalysis for the hydrolysis of ammonia borane (H NBH , AB) with a turnover frequency (TOF) of 4896.8 h and an activation energy (E ) of 18.8 kJ mol . The NiPd-NG-S catalyst is also highly active for catalyzing the transfer hydrogenation from AB to nitro compounds, leading to the green synthesis of quinazolines in water. Our assembly method can be extended to other graphene and NP catalyst materials, providing a new 2D NP catalyst platform for catalyzing multiple reactions in one pot with maximum efficiency.
我们报告了一种将氮掺杂石墨烯 (NG) 和纳米粒子 (NPs) 的单层阵列组装并随后转移到固体基底 (S) 上的简便方法。我们以 3nm 的 NiPd NPs 为例，证明了 NiPd-NG-Si（Si=硅片）可以作为催化剂，并在氨硼烷 (H2NBH3，AB) 的水解中表现出最大的 NiPd 催化作用，其转化率频率 (TOF) 为 4896.8 h-1，活化能 (E) 为 18.8 kJ·mol-1。NiPd-NG-S 催化剂也对 AB 到硝基化合物的转移氢化具有很高的活性，可在水中绿色合成喹唑啉。我们的组装方法可以扩展到其他石墨烯和 NP 催化剂材料，为在一个锅中以最高效率催化多种反应提供了一个新的 2D NP 催化剂平台。
