A novel double S-scheme photocatalyst Bi7O9I3/Cd0.5Zn0.5S QDs/WO3-x with efficient full-spectrum-induced phenol photodegradation

Xin Chen et al.

Summary: A Bi7O9I3/Cd0.5Zn0.5S QDs/WO3-x ternary heterojunction with full spectrum response was prepared and applied in the photodegradation of phenol. The heterojunction showed the highest performance under full spectrum, visible, and near-infrared light irradiation, with reaction rates 4.02, 3.75, and 5.71 times higher than pure Bi7O9I3, respectively. This improvement is attributed to the construction of a double S-scheme heterojunction and full-spectrum response, allowing for effective charge distribution and migration as well as excellent response to sunlight.
