Fabrication of a highly efficient CuO/ZnCoO/CNTs ternary composite for photocatalytic degradation of hazardous pollutants.

In the current study, CuO, ZnCoO, CuO/ZnCoO, and CuO/ZnCoO/CNTs photocatalysts were prepared to remove crystal violet (CV) and colorless pollutants (diclofenac sodium and phenol) from wastewater. Herein, sol-gel and co-precipitation methods were used to synthesize CuO and ZnCoO, respectively. The sonication method was used to synthesize CuO/ZnCoO and a CNTs-based composite (CuO/ZnCoO/CNTs).
