“…Among these factors is the difficulty of recovering and recycling the catalyst in a homogeneous process, which is one reason why heterogeneous catalysts are preferred for PMS activation. The main advantages of these heterogeneous catalysts are as follows: (i) reusability and easiness for the separation from the reaction system; (ii) minimum release of metal catalyst that could be considered as a secondary pollutant; (iii) ability to operate in extreme conditions; (iv) higher effectiveness at a low economical cost [9][10][11]. Among the heterogeneous catalysts, metal-organic frameworks (MOFs) have drawn great interest because of their high surface area, enormous framework flexibility, and huge structural variety, which facilitate the development of tailored properties materials, as well as tunable pore sizes and catalytic activities [12,13].…”

In this study, three CuFe-MOFs were successfully synthesized by a solvothermal process by changing the ratio of solvents, salts, or temperature. These MOFs named CuFe(BDC-NH2)R, CuFe(BDC-NH2)S, and CuFe(BDC-NH2)D showed rod-shaped, spindle-like, and diamond-like structures, respectively. The CuFe(BDC-NH2)D and CuFe(BDC-NH2)S were found to exhibit an improved PMS activation for Rhodamine B removal attaining levels around 92%. Their effective removal capability was investigated as a function of the pH, catalyst dosage, and the effect of the application of UV radiation. The best degradation system was photo-assisted activation of PMS when CuFe(BDC-NH2)D and CuFe(BDC-NH2)S were used. Under these conditions, the degradation of a mixture of antibiotic and anti-inflammatory drugs (sulfamethoxazole and antipyrine) was evaluated with the results revealing the total degradation of both drugs after 1 h. A higher antibacterial activity was attained with the system CuFe(BDC-NH2)R/PMS due to the high copper content with respect to the others.
