A two-dimensional (2D) Janus film with self-assembled gold nanoparticles (AuNPs) is a class of fascinating materials that may offer unprecedented opportunities to realize diverse applications due to their two distinct faces with anisotropic properties. In this work, we report a novel, straightforward strategy for the preparation of a bilayer coordination nanosheet (CONASH)/AuNP Janus film, where the CONASH features infinite trinuclear gold(I) pyrazolate cyclic complexes with electron-accepting viologen as bridges. The bilayer film has visible light absorption and redox properties and showcased promising photocatalytic H evolution activity by virtue of the formed unique heterojunction structure between AuNPs and CONASH. The current study opens a novel pathway for controlled fabrication of the 2D Janus film with assembled AuNPs for photocatalytic applications.
一种带有自组装金纳米颗粒（AuNP）的二维（2D）Janus薄膜是一类引人入胜的材料，由于其具有两个具有各向异性性质的不同面，可能为实现各种应用提供前所未有的机会。在这项工作中，我们报告了一种制备双层配位纳米片（CONASH）/AuNP Janus薄膜的新颖、直接的策略，其中CONASH具有以电子接受性紫精为桥的无限三核金（I）吡唑啉环配合物。该双层薄膜具有可见光吸收和氧化还原性质，并且由于在AuNP和CONASH之间形成了独特的异质结结构而展现出有前景的光催化析氢活性。当前的研究为用于光催化应用的带有组装AuNP的二维Janus薄膜的可控制备开辟了一条新途径。
