Preparation of AgPO/CoWO S-scheme heterojunction and study on sonocatalytic degradation of tetracycline.

In this study, 0.6AgPO/CoWO composites were synthesized by hydrothermal method. The prepared materials were systematically characterized by techniques of scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffractometer (XRD), X-ray photoelectron spectroscopy (XPS), N adsorption/desorption, and UV-vis diffuse reflectance spectrum (DRS).
