Rhodamine B (RhB) is a highly toxic dye that poses significant health risks. In this study, CuZn-ZIFs was synthesized and analyzed by various techniques such as Powder X-ray diffraction (PXRD), Fourier-transform infrared spectroscopy (FT-IR), Thermogravimetric analysis (TGA), Scanning electron microscopy (SEM), energy-dispersive X-ray spectrometer (EDS) and Brunauer–Emmett–Teller (BET). In clearly defined technical parameters, CuZn-ZIFs exhibited a notable heat resistance up to 600°C and featured a distinct polygonal structure. Furthermore, an assessment revealed a Specific Surface Area of 1242.7 m²·g^-1, accompanied by a pore volume of 0.47 cm³·g^-1, a pore size measuring 11.53 Å, and an average particle size of 28.67 nm. Not only that, it was found to be effective in promoting the oxidation of peroxymonosulfate (PMS) for RhB treatment. The results showed that over 90% of RhB concentration 40 mg·L^-1 was degraded within 50 minutes in the presence of PMS and 0.15 g·L^-1 of CuZn-ZIFs catalyst at room temperature. Additionally, the catalyst demonstrated remarkable reusability, maintaining high removal efficiency after five cycles. It indicated that this material has great potential as an effective heterogeneous catalyst for removing toxic dyes from aqueous solutions.
