Abstract
This research aimed to synthesize zinc oxide/bismuth oxychloride (ZnO/BiOCl) composites with ratios of 1:1, 1:2, and 2:1 by weight, to characterize the synthesized composites and to study photocatalytic rhodamine B dye degradation capability of the synthesized composites. The ZnO/BiOCl composites were synthesized by microwave radiation. Characterization of the synthesized ZnO/BiOCl composites were performed using X-ray diffraction (XRD), Field emission scanning electron microscope (FESEM), Energy dispersive X-ray analysis (EDX), Fourier transform infrared spectroscopy (FTIR) and Specific surface area analysis (BET). Photocatalytic degradation of rhodamine B dye of the synthesized ZnO/BiOCl composites were conducted using UV-Vis spectrophotometer. XRD analysis of the ZnO/BiOCl composites with all ratios of ZnO and BiOCl demonstrated diffraction peaks showing the hexagonal phase of zinc oxide and the tetragonal phase of bismuth oxychloride. Furthermore, it was also found that the ZnO/BiOCl composite with a ratio of 1:1 by weight was a sheet-like composite material with the highest specific surface area of 581.48 square meters per gram and the best efficiency in degrading rhodamine B dye of 69.97 percent in 120 minutes under light condition.
