Abstract
In this study, camphoric acid was used as a carbon source in the synthesis of the catalyst for the first time. The new Fe3O4/C/SiO2/TiO2 and Fe3O4/C/TiO2 magnetic nano-semiconductors were synthesized and used for hydrogen peroxide-free photodegradation of polychlorinated biphenyls (PCBs) in transformer oil (Askarel) and significant PCB 138 in aqueous solutions under visible light irradiation. Also, interestingly, direct degradation was carried out for Askarel oil in addition to the extraction-degradation method. These nano-reduced band gap semiconductors (2.10 eV) were characterized by field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), N2 adsorption-desorption isotherm analyses, and vibrating sample magnetometer (VSM). The high photocatalytic performance compared to Fe3O4/C/TiO2 and P25 in direct and indirect (extraction-degradation) degradation besides its convenient magnetic recovery are the main advantages of Fe3O4/C/SiO2/TiO2. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.
