Investigation of the photocatalytic potential of CuFe₂O₄ embedded on a g-C₃N₄ nanosheet toward malachite green (MG) dye

This study produced a hetero-structured nanocomposite consisting of CuFe₂O₄ (CFO) supported on g-C₃N₄ (g-CN) with high photocatalytic properties through hydrothermal technique. Various analytic methods were operated to investigate the physicochemical characteristics of the created nanocomposite. The photocatalytic potential of the synthesized materials was concluded with the degradation efficiency of malachite green (MG) dye under a visible source. The photocatalytic revealed that the CuFe₂O₄/g-C₃N₄ has a degradation efficiency of up to 94.79% compared to pure CuFe₂O₄ (66.43%) and g-C₃N₄ (73.95%). The stability of the composite photocatalyst was demonstrated by its consistent 89.77% efficiency across five cycles. According to the scavenger study, the photodegradation of dye species is caused by several reactive species, including holes, superoxide anion, and hydroxyl radicals. The finding indicates that the CuFe₂O₄/g-C₃N₄ exhibited high photocatalytic potential and it can also be employed in various electrical and magnetic properties.
