title: Carbon dot and BiVO4quantum dot composites for overall water splitting via a two-electron pathway.
abstract: Carbon dot and BiVO4quantum dot composites (CDs/BiVO4QDs) show a significantly improved photocatalytic activity and high stability for overall water splitting. By using 5% CDs/BiVO4QDs as photocatalysts, the H2evolution 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 BiVO4QDs (0.21 μmol h-1). Note that, for the CD/BiVO4QD catalyst, the produced H2and O2are approximately equal to the stoichiometric ratio (H2: O2= 1.80 : 1), while that of BiVO4QDs is nonstoichiometric (about only 0.06 : 1). In addition, the present water splitting occurs via a two-electron pathway and CDs and BiVO4QDs served as the reduction and oxidation reaction active sites, respectively.
