摘要：
High content oxygen vacancies BiOCl consisted of thinner nanosheets was successfully synthesized assisted with ammonium sulfamate (AS) via a facile solvothermal route. X-ray powder diffractometer (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscope (TEM), UV-Vis diffused reflectance spectra (DRS), temperature programmed oxidation (O-2-TPD), photoluminescence (PL), electrochemical impedance spectroscopy (EIS), and electron spin resonance (ESR) were applied to characterize the structure, morphology as well as the physicochemical properties of as-synthesized samples. The results confirm that AS and the mix solution pH have great effect on the BiOCl properties. BOC-2 (k = 0.484 min(- 1)) due to its high content oxygen vacancies exhibits 23 times high visible photocatalytic performance than BOC (k = 0.021 min(- 1)) for degradation of Rhodamine B (RhB), and enhanced photodegradation of antibiotic tetracycline hydrochloride (TC-HCl) solution. This work provides new insights on controllable synthesis of highly active BiOCl with different content oxygen vacancies.
