The correlation between structure and properties in the photodegradation reaction of bismuth oxychloride (BiOCl) was explored this work. Three BiOCl samples with different sizes, morphological structures, defects were prepared through a hydrothermal method experimental manipulation. Their structural comprehensively characterized using X-ray diffraction, scanning electron microscopy, transmission spin resonance, photoelectron spectroscopy, Fourier transform infrared ultraviolet–visible diffuse reflectance photoluminescence. Taking tetracycline hydrochloride (TC-HCl) as probe reaction, we found that high activity could be achieved by decreasing their crystal size thickness, introducing proper structure, assembling nanosheets to get microball structure. Combined radical-scavenge experiments resonance (ESR) spin-trap spectra, conclude ̇O2– dominant reactive oxygen species for degradation reaction. detailed pathway TC-HCl further analyzed liquid chromatography–mass spectrometry.
