Abstract:
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 H2 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.
