摘要：

Z-scheme photocatalytic system is an efficient way to achieve high efficiency photocatalytic overall water splitting. However, the acquisition of efficient Z-scheme visible-light photocatalysts is still a huge challenge at present due to the inactive visible light-active component and various low-band-gap for semiconductors. Herein, we constructed the BiVO₄/CDs/CdS Z-scheme photocatalyst with carbon dots(CDs) as solid-state electron mediator, which exhibits excellent photocatalytic activity and stability for photocatalytic overall water splitting under visible light. The BCC50 (BiVO₄/CDs/CdS with the mass ratio of BiVO₄/CdS = 50%) as photocatalyst shows the best photocatalytic activity with stoichiometric ratio of H₂ evolution rate of 1.24mmol/h and O₂ evolution rate of about 0.61mmol/h. The enhanced photocat-alytic activity of the Z-scheme photocatalyst can be attributed to high efficiencies for separation and transport of photogenerated charge carriers and extended the lifetime of electrons and holes.
