Highly Efficient Mg 0.75 Ce 0.25 Fe 12 O 19 @ZIF-67 Heterojunction Co-catalyst for Photo-reduction of Rhodamine B
Abstract
This research presents a comprehensive investigation into the synthesis and application of novel composite photocatalysts,
namely Mg 0.75 Ce 0.25 Fe 12 O 19 @ZIF-67 for the degradation of Rhodamine B (RhB) dye under sunlight irradiation. The synthesis
involved the preparation of Mg 0.75 Ce 0.25 Fe 12 O 19 and ZIF-67 frameworks, followed by the fabrication of the composite
catalyst. Various characterization techniques, such as XRD, SEM, EDX, and FTIR, were employed to assess the structural,
morphological, and compositional properties of the synthesized materials. Photocatalytic experiments were conducted
to evaluate the effi ciency of the catalysts in degrading RhB, revealing remarkable enhancement in degradation effi ciency
(90%) using the composite photocatalyst compared to individual components. The eff ects of catalyst type, dosage, and pH
on the degradation process were systematically investigated. Furthermore, a proposed mechanism elucidated the role of the
Mg 0.75 Ce 0.25 Fe 12 O 19 @ZIF-67 cocatalyst for RhB degradation under solar light, highlighting the generation of radicals as
key contributors for degradation process.
