This work synthesized and used bimetallic FeCo-ZIFs as a potentially effective heterogeneous catalyst for removing dangerous contaminants from water, focusing on the color indigo carmine (IC). The physicochemical properties of FeCo-ZIFs were determined by various techniques such as SEM, FT-IR, PXRD, EDX, and nitrogen adsorption-desorption. FeCo-ZIFs have a polyhedral crystalline structure, good crystallinity, a relatively uniform particle size distribution, and remarkable thermal stability over 550 °C. The catalytic effectiveness of FeCo-ZIFs was assessed through the advanced oxidation processes (AOPs) for IC removal.  It was found that the FeCo-ZIFs/PDS system could efficiently remove approximately 97.5 ± 0.3 % of IC (30 mg.L^-1) within just 20 minutes at room temperature, with FeCo-ZIFs and PDS dosages 0.25 g.L^-1 and 0.1 g.L^-1, respectively. Crucially, the bimetallic catalyst's recyclability was evaluated, and the findings showed that FeCo-ZIFs retained about 91.4 ± 2.5 % efficiency after four cycles without exhibiting appreciable structural alterations from the original material.
