Description	Journal: Nanotechnology Inspired by natural photosynthesis, the artificial heterojunction photocatalysts have been extensively studied. Herein, a novel ternary g-C3N4/Pt/BiVO4 photocatalytic system was successfully synthesized, where Pt@BiVO4 nanosheet is anchored on the surface of layered graphitic carbon nitride (g-C3N4) as evidenced by structural observations. Ultraviolet photoelectron spectroscopy (UPS) and UV-Visible diffuse reflectance spectroscopy (UV-vis DRS) are carried out to identify the position of the conduction band (CB) and valence band (VB). A Z-scheme is used to interpret the superior photocatalytic performance of g-C3N4/Pt/BiVO4 and further verified by the capture of free radicals and terephthalic acid photoluminescence experiments. Compared with the g-C3N4/BiVO4 binary system, the Z-scheme g-C3N4/Pt/BiVO4 photocatalyst possesses not only enhanced carriers separation efficiency but also maintains sufficient redox properties, thus inducing the superior photocatalytic activity. More importantly, the novel Z-scheme photocatalyst exhibit excellent recycle stability, which can provide inspiration on the rational design of efficient and practical photocatalyst in environmental pollution treatment. Ternary photocatalyst also exhibits significantly enhanced visible-light photocatalytic hydrogen production performance.
