Preparation and visible photocatalytic properties of Ag3PO4/PBN/ Fe3O4 composites

The research that produced and examined composites made of silver phosphate (Ag3PO4), porous boron nitride (PBN), and ferrosoferric oxide (Fe3O4) was presented in this report. Several tests, including FT-IR, Raman, oS, SEM, and TEM, have produced data that show PBN and Fe3O4 are evenly distributed on the surface of Ag3PO4. The band gap energies and absorption spectra of Ag3PO4/PBN/Fe3O4 composites are comparable to those of Ag3PO4 according to UV-Vis analysis. Additionally, specific surface analysis shows that the Ag3PO4/PBN/Fe3O4 composites have less surface area and pore volume than Ag3PO4/PBN. By preventing photogenerated electrons and holes from complexing, the composites are shown to have increased photocatalytic activity in photoluminescence studies. Hysteresis curves reveal the magnetic characteristics of the composites in magnetic examination of vibrating samples. In addition, Under visible -light irradiation, 99.7 % of Rhodamine B is degraded during the first 10 min. After five cycling tests, the results show that the composites have good cycling stability and negligible activity loss. Finally, a potential photocatalytic degradation pathway is suggested in the paper.
