Layered double hydroxides (LDHs) have received substantial research as manufacturing innovation and prospective photocatalysts for the degradation of organic contaminants due to large surface area, strong anionic exchange capacity, and tunable composition. In this study, we modified Mg/Al-LDHs with Ni and Cr to further enhance their performance in removing Methyl Orange (MO) an anionic dye widely used in textiles, cosmetics, and healthcare products. The modified Mg/Al-LDHs were synthesized using hydrothermal co-precipitation method and characterized by Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscope (TEM), and X-ray diffraction (XRD). The breakdown rate of MO under solar light was used for evaluating the material's photocatalytic activity. The outcomes demonstrated that the Ni/Mg/Al/Cr (LDH-4) photocatalysts degraded MO more quickly than the undoped substance. The addition of Cr to the Ni/Mg/Al matrix caused the band gap to develop new energy levels, which increased the material's photocatalytic activity. The Ni/Mg/Al doped with Cr has demonstrated tremendous potential as a photocatalysts for the MO degradation.
