Beschreibung:
Via solvothermal-precipitation method with reducer glucose was to construct AgBiO3/Bi5O7I-OVs heterojunction. Among, the OVs play a key role in achieving local electronic control goals, and perovskite AgBiO3 is an important element for visible light driving the performance of the photocatalyst. Moreover, EPR and PL proved the existence of oxygen vacancies (OVs); UV-Vis, EIS, and PT verified change in terms of electronic construction and light absorption characteristics. Tetracycline (TC) and ciprofloxacin (CIP) were selected as goal pollutants to studying photocatalytic properties. B2ABO exhibits the best photo-catalytic performance and the separation and transfer of e- and h+. The activity improvement in this work is mainly attributed to the generation of oxygen vacancies, and perovskite broadens the visible light absorption range, which effectively suppresses the recombination of carriers. The trapping experiments, kinetic study and photocatalytic mechanism were carried out to deeply comprehend the excellent performance. Therefore, it is forward-looking to promote an in-depth understanding of high-performance Bi-based semiconductor photocatalysts
