Abstract

Herein, an Ag@g-C₃N₄/MoS₂ heterostructure is successfully synthesized for efficient solar-to-water oxidation. UV-vis DRS and steady-state PL analyses reveal the narrow band gap (2.10 eV) and efficient charge separation properties of the Ag nanoparticles and MoS₂, respectively. The benefits include an excellent ∼3.2-fold increase in O₂ production rate (2727 μmol g⁻¹ h⁻¹) compared to Ag@g-C₃N₄. A plausible Z-scheme mechanism is also proposed.
