The development of cost-effective, non-toxic and efficient catalysts for carbon monoxide (CO) oxidation under low-temperature conditions is a pressing challenge in modern materials science, particularly for air purification systems designed for enclosed human-inhabited environments. In this study, a systematic approach was applied to design and synthesize mono-, bi-, and trimetallic metal–organic frameworks (MOFs) incorporating Fe, Ce, and Cu ions with ethylenediaminetetraacetic acid (EDTA) as a multidentate organic linker. The materials were prepared via solvothermal synthesis at 170 °C and subsequently dried at 105 °C. Among the series, the trimetallic MOF-170(FeCeCu)-105 exhibited the highest catalytic activity. Comprehensive characterization using PXRD, FTIR, SEM, EDXS, elemental mapping, and N2 physisorption revealed a hybrid structure consisting of crystalline MOF types and amorphous mixed-metal oxides, with a mean particle size of ∼2.5 μm, specific surface area of 97.9 m2/g, and total pore volume of 0.253 cm3/g. Catalytic performance tests in a continuous-flow reactor showed ∼90 % CO conversion at 170 °C with stable activity maintained over 10 h. Comparative analysis indicated a clear enhancement in activity for the trimetallic system over its mono- and bimetallic counterparts, confirming the synergistic interaction among the metal ion centers. In vitro experiments conducted on human THP-1 monocytes, B16-F10 melanoma cells and K-562 lymphoblast cells showed a high biocompatibility of the developed catalyst. These results establish MOF-170(FeCeCu)-105 as a promising multifunctional material for safe and effective CO removal in air purification technologies.
