Investigation of the Photocatalytic Performance, Mechanism, and Degradation Pathways of Rhodamine B with Bi₂O₃ Microrods under Visible-Light Irradiation.

ABSTRACT: In the present work, the photodegradation of Rhodamine B with different pH values by using Bi₂O₃ microrods under visible-light irradiation was studied in terms of the dye degradation efficiency, active species, degradation mechanism, and degradation pathway. X-ray diffractometry, polarized optical microscopy, scanning electron microscopy, fluorescence spectrophotometry, diffuse reflectance spectra, Brunauer-Emmett-Teller, X-ray photoelectron spectroscopy, Fourier-transform infrared spectroscopy, UV-visible spectrophotometry, total organic carbon, and liquid chromatography-mass spectroscopy analysis techniques were used to analyze the crystal structure, morphology, surface structures, band gap values, catalytic performance, and mechanistic pathway. The photoluminescenc
