In this study, two metal-organic frameworks (MOFs), and ,were synthesized by hydrothermal. In these frameworks, 5-amino isophthalic acid and 4,4’-bipyridine act as linkers. Copper (II) acetate monohydrate and cobalte (II) tetrahydrates as metal sources build nodes in these frameworks. The optical properties of the prepared frameworks were studied by DRS. The energy band gap values for [Co(5-aip)(bpy)0.5].H2O and [Cu(5-aip)(bpy)0.5].H2O were 2.3 and 2.8 eV, respectivly. Then the catalytic degradation of methylene blue and methyl orange as pollutants was investigated. The percentage of degradation of methylene blue and orange-methyl pigments with Cu-based metal-organic framework after 180 minutes was 82.75% and 64.03% and for the Co-based metal-organic framework was 98.64% and 64.03% , respectively. The obtained structures were charactrized by using Fourier transform infrared (FT-IR), Elemental analyses (CHN), Atomic absorption analysis (AAS), X-ray diffraction (XRD), Scanning electron microscopy (SEM), Thermal gravimetric analysis (TGA), Energy dispersive spectrometr (EDS) mapping analysis (MAP). The band gap of the samples was calculated by UV-Vis diffiase reflectance spectra (DRS).
