In this research project, using the prepared hydrothermal synthesis method, the metal compound BiCoO3 was prepared for the first time. In the next step, the organic-metal compound PCN-22 was prepared both specifically an‎d as a nanocomposite BiCoO3/PCN-222. The metal oxide BiCoO3 alone has a suitable ability to degrade photocatalysis. On the other han‎d, the metal-organic PCN-222 shows better photocatalysis than the pure metal due to its higher surface area. The 2-metal-organic compound PCN22, despite having a suitable ban‎d gap for activity in the visible light region an‎d also a suitable surface area due to the rapid electron-hole recombination in its structure, has the potential to be used as a photocatalytic compound. By combining the two desired samples an‎d forming the nanocomposite BiCoO3/PCN-222, the reaction efficiency was increased by preventing electron-hole recombination. Also, by forming the BiCoO3/PCN-222 nanocomposite, a smaller amount of organoporphyrin metal PCN-222 is used to perform the photocatalytic degradation reaction, which makes this nanocomposite economically viable.The photocatalytic nanocomposite showed good degradation capability in the visible light range, as it degraded 100% of the pollutant compound methylene blue with 10 ppm in 1.5 hours under visible light irradiation of a 15-watt LED lamp. Also, in this study, the effect of factors on the reaction efficiency such as the amount of photocatalyst, reaction time, an‎d pH was investigated.
