In this paper, to the utilization of the solar light as an unlimited and clean source of Energy, novel Ag₂CrO₄/Cu(BDC) metal-organic framework (MOFs) photocatalyst with different mass percentages of Cu(BDC) were synthesized for water purification applications under simulated solar light. The precipitation method was used to synthesize the Ag₂CrO₄/Cu(BDC) photocatalysts. Some techniques such as XRD, FESEM, EDX, TEM, BET-BJH, FTIR, DRS, and pHpzc were performed to determine the prepared samples' structural, chemical and optical properties. For instance, BET-BJH analysis outcomes illustrated that bare Ag₂CrO₄ has a low surface area that impedes the absorption of pollutant molecules. Whereas Ag₂CrO₄/Cu(BDC)(50) sample, due to the presence of Cu(BDC) and appropriately dispersion of Ag₂CrO₄ particles over Cu(BDC), has a vast specific surface area, pore-volume, pore diameter. Furthermore, DRS analysis demonstrated that Ag₂CrO₄/Cu(BDC)(50) has narrower bandgap energy in comparison with bare Cu(BDC) and it is capable of absorbing light in the visible light region. Additionally, the synthesized samples were considered for the solar-light-driven removal of different organic dyes like Acid Orange 7, Methylene blue, and Rhodamine B. The tremendous enhanced photocatalytic performance under the simulated solar light with 98% removal of AO7 was seen over Ag₂CrO₄/Cu(BDC)(50) sample. Then, the effect of initial solution pH, photocatalyst dosage, and initial dye concentration were studied as crucial parameters on photocatalytic performance. Finally, the reaction mechanism of AO7 degradation over Ag₂CrO₄/Cu(BDC)(50) was proposed.
