catalytic activity of the QDs. In addition, the influence of graphene oxide (GO) and graphitic carbon nitride (g-
C3N4) was assessed on the photocatalytic activity of the ZnS QDs through degradation of acid red 14 (AR14) and
bisphenol-A (BA) under visible light. Higher photocatalytic degradation efficiency (97.1% for AR14 and 67.4%
for BA within 180 min) and higher total organic carbon (TOC) removal (67.1% for AR14 and 59.2% for BA
within 5 h) was achieved in the presence of ZnS QDs/g-C3N4 compared with ZnS QDs/GO nanocomposite.
Finally, the Gd-doped ZnS QDs were hybridized with g-C3N4 as optimal support to fabricate a potent visible-lightdriven
photocatalyst for the decomposition of organic contaminants. The maximum photocatalytic degradation
of 99.1% and 80.5% were achieved for AR14 and BA, respectively, in the presence of Gd-doped ZnS QDs/g-C3N4
