Abstract

Metallic-phase molybdenum disulfide (1T-MoS2) nanosheets have proven to be highly active in the hydrogen evolution reaction (HER). We describe construction of photosensitizer functionalized 1T-MoS2 by covalently tethering the molecular photosensitizer [RuII(bpy)3]2+ (bpy=2,2′-bipyridine) on 1T-MoS2 nanosheets. This was achieved by covalently tethering the bpy ligand to 1T-MoS2 nanosheets, and subsequent complexation with [RuII(bpy)2Cl2] to yield [RuII(bpy)3]–MoS2. The obtained [RuII(bpy)3]–MoS2 nanosheets were characterized using infra-red, electronic absorption, X-ray photoelectron, and Raman spectroscopies, X-ray powder diffraction and electron microscopy. The fabricated material exhibited a significant improvement of photocurrent and HER performance, demonstrating the potential of such two-dimensional [RuII(bpy)3]–MoS2 constructs in photosensitized HER.
