通过多步反应合成了由 MoC 纳米粒子修饰的各向异性铌酸盐层组成的杂化物。层状己铌酸盐的逐步层间反应诱导交替层间的选择性表面改性，随后的超声处理导致双层纳米片的形成。双层纳米片的进一步液相MoC沉积导致了MoC纳米颗粒在双层纳米片表面的装饰。这种新的混合体可以被视为两层具有各向异性改性纳米颗粒的堆叠。 MoC合成中相对较高的温度导致接枝膦酸酯基团部分浸出。由于部分浸出而暴露的铌酸盐纳米片表面可能与 MoC 相互作用以成功杂交。加热后的杂化物表现出光催化活性，表明这种杂化方法可用于半导体纳米片和助催化剂纳米颗粒的杂化合成，以实现光催化应用。
The hybrid composed of anisotropic niobate layers modified with MoC nanoparticles is synthesized by multistep reactions. The stepwise interlayer reactions for layered hexaniobate induce selective surface modification at the alternate interlayers, and the following ultrasonication leads to the formation of double‐layered nanosheets. The further liquid phase MoC deposition with the double‐layered nanosheets leads to the decoration of MoC nanoparticles on the surfaces of the double‐layered nanosheets. The new hybrid can be regarded as a stacking of the two layers with anisotropically modified nanoparticles. The relatively high temperature in the MoC synthesis causes partial leaching of the grafted phosphonate groups. The exposed surface of the niobate nanosheets due to the partial leaching may interact with MoC to succeed in the hybridization. The hybrid after heating exhibits photocatalytic activity, indicating that this hybridization method can be useful for hybrid synthesis of semiconductor nanosheets and co‐catalyst nanoparticles toward photocatalytic application.
