Synthesis of CuFe‐LDH/MIL‐88 Composite for the Photocatalytic Degradation of Methyl Orange Dye

Abstract In this study, CuFe‐LDH/MIL‐88 composite was prepared via the hydrothermal method with low cost and high efficiency for methyl orange (MO) degradation. The produced photocatalysts were characterized for their morphological and structural aspect employing the XRD, FTIR, SEM, and EDX techniques. Through SEM analysis, it was established that the synthesized LDH materials had a rod‐like morphology and a layered, stacked structure. In order to confirm the working efficiency of the synthesized CuFe‐LDH/MIL‐88 composite, various factors including the contact time and pH of the MO solution were evaluated. The results demonstrated that the CuFe‐LDH/MIL‐88 composite photocatalyst exhibited 66.66% of MO degradation under 60 min of solar light irradiation. Besides, the photocatalysts also showed high stability and recyclability; the activity remained almost unchanged after four regeneration processes. The findings of this work offer important mechanistic information concerning the preparation of high‐performance photocatalysts and manifest a great promise in environmental applications.
