摘要：

Carbon dot and BiVO₄ quantum dot composites (CDs/BiVO₄ QDs) show a significantly improved photocatalytic activity and high stability for overall water splitting. By using 5% CDs/BiVO₄ QDs as photocatalysts, the H₂ evolution of 0.92 μmol h⁻¹ , was achieved under solar light irradiation without any cocatalysts or sacrificial reagents, which is about 4 times that of BiVO₄ QDs (0.21 μmol h⁻¹ ). Note that, for the CD/BiVO₄ QD catalyst, the produced H₂ and O₂ are approximately equal to the stoichiometric ratio (H₂ : O₂ = 1.80 : 1), while that of BiVO₄ QDs is nonstoichiometric (about only 0.06 : 1). In addition, the present water splitting occurs via a two-electron pathway and CDs and BiVO₄ QDs served as the reduction and oxidation reaction active sites, respectively.
