Synthesis and photocatalytic degradation efficiency of MgFe2O4@CuO nanocomposite for Bromophenol blue dye removal

Abstract

Rapid advances in science and technology have made life easier, but they have also brought forth a number of issues that put both living things and non-living objects at risk. In this work, MgFe₂O₄@CuO has been synthesized via the co-precipitation method to minimize the creation of environmentally unfavorable gases, demonstrating the need for materials that may be used for both purposes. Particularly, the nanocomposite MgFe₂O₄@CuO aims at the removal of Bromophenol blue (BPB) dye. Utilizing FTIR, XRD, EDX and SEM, the as-synthesized material was examined. Therefore, a number of parameters, including contact duration, pH activity, etc., were thoroughly examined in order to measure the effectiveness of photocatalytic degradation. The photocatalytic degradation efficiency of the composite is noticed to be 52.68%, 66.65%, and 90.94% at 15, 30, and 45 min, respectively. Of all the samples, the composite heterojunction exhibits the highest photocatalytic degradation efficiency. According to the results, magnetic ferrite in a heterojunction enhances charge transfer, decreases electron–hole recombination, and increases radiation absorption. The Results of this work exhibit the efficiency of MgFe₂O₄@CuO for industrial wastewater treatment. As a result, the synthesized material is both affordable and useful for a variety of tasks.
