A composite DUT-8(Zn/Ni)/CeO2 photocatalysts were configured using a simple and facile hydrothermal method and characterized using PXRD, SEM, BET, FTIR and Photoluminescence studies to configure their morphological, structural as well spectroscopic characteristics. The as obtained composites demonstrate superior photocatalytic activity for the degradation of dichlorophenols (2, 4 and 2, 6 DCP). The introduction of MOF into the semiconductor oxide proliferate the photocatalytic activity owing to a strong interface between the two that promotes the transfer as well as the separation of photo generated charge carriers. These nanocomposites DUT-8(Zn)@CeO2 and DUT-8(Ni)@CeO2 appear highly promising then the individual counterparts as they record the photodegradation efficiency of (86%, 89%) for 2,4-DCP, and (85%, 91%) for 2,6-DCP respectively at optimal conditions (concentration of pollutants-5mg/L; catalyst dose-0.6 g/L and pH-8). The practical applicability of the nanocomposites was evaluated using mineralization study involving the industrial effluents of the paper mill industry. Notably, the mineralization of chlorophenols (85.3% for 2,4-DCP, and 87% for 2,6-DCP) was observed in case of DUT-8(Zn)@CeO2 and DUT-8(Ni)@CeO2 nanocomposites. Besides, the synthesized photocatalysts show high stability and reusability for over five experimental cycles.
