The oxidation of 5-HMF to HMFCA is an important yet complex process, as it generates high-value chemical intermediates. Achieving this transformation efficiently requires the development non-precious, highly active catalysts derived from renewable biomass sources. In work, we introduce UoM-1 (UoM, University Mazandaran), a novel cobalt-based metal-organic framework (Co-MOF) synthesized using simple one-step ultrasonic irradiation method. synthesis employed ligand 4,4'-((1E,1'E)-((5-carboxy-1,3-phenylene)bis(azaneylylidene))bis (methaneylylidene))dibenzoic acid (H3bdda). A comprehensive suite analytical techniques, including FT-IR, EDX, ICP, XRD, TEM, DLS, FESEM, and BET-BJH, was used confirm structural integrity material. catalytic performance investigated for selective conversion HMF HMFCA, demonstrating its effectiveness low-cost, accessible catalyst. To promote more sustainable environmentally friendly approach, reactions were performed in deep eutectic solvents, which offer green, low-energy alternative traditional solvents. This study shows that catalyst not only provides economical solution but also aligns with modern green chemistry principles, making promising candidate future applications.
