Fe-MOF derivative photocatalyst with advanced oxygen reduction capacity for indoor pollutants removal

Fe-MOF derivative (M-300) is successfully prepared by thermal treatment using MIL-100(Fe) as a precursor. The resulting M-300 catalyst displays excellent performance in the degradation of volatile organic compounds (VOCs) and the bacteriostasis to Escherichia coli under the visible light. In addition, the catalyst also exhibits the capacity of acetaldehyde degradation under actual sunlight. The high activity is attributed to the abundant exposure of the unsaturated Fe 2+ active site, which can significantly promote the transfer of photogenerated electron and the oxygen reduction process, thus improving the efficiency of the entire photocatalytic oxidation reaction. This work shows the application prospect of MOFs derivatives in the field of indoor photocatalytic purification, and also provides a new insight into the study of catalyst modification in photocatalytic degradation of pollutants.
