Oxygen Vacancy-Mediated CuWO/CuBiO Samples with Efficient Charge Transfer for Enhanced Catalytic Activity toward Photodegradation of Pharmacologically Active Compounds.

Photocatalytic degradation is a promising method for controlling the increasing contamination of the water environment due to pharmacologically active compounds (PHACs). Herein, oxygen vacancy (OV)-modulated Z-scheme CuWO/CuBiO hybrid systems were fabricated thermal treatment by loading of CuWO nanoparticles with OVs on CuBiO surfaces. The synthesized CuWO/CuBiO hybrid samples exhibited an enhanced photodegradation ability to remove PHACs under visible-light irradiation.
