The CoMn₂O₄ binary metal oxide with a spinel structure was synthesized from metal-organic framework (MOF) prepared using both microwave-assisted and hydrothermal methods. The time to synthesize MOF by hydrothermal method is much longer than that of the microwave-assisted method. Synthesized materials were characterized by X-ray diffraction (XRD), fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) surface area. The results showed that the CoMn₂O₄ oxide had high purity and a spherical nanocrystalline morphology with particle sizes ranging from 30 nm to 50 nm. Notably, the specific surface area of the material derived from MOF synthesized using the microwave-assisted method reaches 92,40 m²/g, significantly higher than that of the material synthesized by the hydrothermal method, which is 61,84 m²/g This demonstrates that the microwave-assisted method not only reduces synthesis time but also enhances the specific surface area of the material, which is a crucial factor for applications in catalysis, energy storage, and environmental treatment.
