In this study, mixed-metal metal-organic frameworks (MM-MOFs) containing metal-based porphyrin moieties will be synthesized and characterized. Then, efficiency of MOFs with Co and Ni alone and Co/Ni together in the different molar ratios as nodes with Mn-TCPP and H₂TCPP as a linker in the structure of bimetallic-MOFs were investigated for photodegradation of DHN to Juglone. Also, different effecting factors on photocatalytic activity containing solvent, oxidant, time, and type of lamp, were further optimized for the best MM-MOF. According to the results, Ni_50%/Co_50% TCPP-Mn with the molar ratio of 1:1 of Ni:Co shows the highest efficiency in the photocatalytic process which was up to 66.3% under xenon lamp irradiation with blowing of O₂ as the source of oxidant. Therefore, the presence both of nickel and cobalt in the structure led to a synergistic effect in enhancement of photocatalytic activity application.
