Özet

The objective of this study was to evaluate the photocatalytic degradation of a methylene blue dye solution by Fe–Co based amorphous ribbons with different compositions. In order to assess the photocatalytic activity of the amorphous ribbons, analysis was conducted under UVC, UVA and visible irradiation. The results of the photocatalysis experiments demonstrated that the Fe38Mo ribbon exhibited the highest performance under UVA irradiation, with a degradation efficiency of 24.5%. Ribbon of other compositions exhibited degradation efficiencies ranging between 13%. and 20%. In the context of corrosion analyses, the (Fe42Co42)84Cu1B15 ribbon demonstrated the most robust corrosion resistance, exhibiting an icorr value of 1.62E-05 A cm−2 and a corrosion rate of 26.02 mpy (mils per year). The Mo-doped (Fe63Co13)76Mo8Cu1B15 ribbon exhibited an icorr value of 2.84 × 10−5 A cm−2 and a corrosion rate of 47.95 mpy. The (Fe57Co19)76Mo8Cu1B15 ribbon, which exhibited the lowest corrosion resistance, reached an icorr of 3.92 × 10−5 A cm−2 and a corrosion rate of 65.85 mpy. The impact of FeCo-based alloys, which are renowned for their magnetic properties, on magnetic properties was also examined. The magnetic saturation value of the Fe70 ribbon increased from 2.21 to 2.37 emu cm−2 under UVC irradiation, while the coercivity value decreased from 1.42 Oe to 0.85 Oe. These results suggest that low-cost Fe–Co based amorphous ribbons may have potential for use as an efficient photocatalyst in environmental pollution removal applications.
