The scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images showed the successful preparation of Bi4O5I2 microbars. X-ray diffraction (XRD) patterns of the sample were well indexed to the monoclinic phase of Bi4O5I2. The elemental composition was studied by energy dispersive X-ray spectroscopy (EDS), and it was similar to the theorical formula Bi4O5I2. The synthetized microbars despite of their low visible-light response could degrade up to 92.66% of Bisphenol A under white light-emitting diode (LED) light irradiation. The photocatalytic degradation and mineralization tests showed that Bi4O5I2 microbars could be efficiently used for the degradation of organic chemical pollutants.2023http://zaguan.unizar.es/record/13017010.1016/j.matlet.2023.133888http://zaguan.unizar.es/record/130170oai:zaguan.unizar.es:130170MATERIALS LETTERS 336 (2023), 133888 [4 pp.]by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/embargoedAccess
