Abstract

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 Fe²⁺ 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.

具有先进氧还原能力的Fe-MOF衍生物光催化剂用于室内污染物去除

以MIL-100(Fe)为前驱体，通过热处理成功制备了Fe- mof衍生物(M-300)。所制得的M-300催化剂在可见光下对挥发性有机物(VOCs)的降解和对大肠杆菌的抑菌性能优异。此外，该催化剂还显示出在实际阳光下乙醛降解的能力。高活性是由于大量暴露不饱和Fe2+活性位点，能显著促进光生电子的转移和氧还原过程，从而提高整个光催化氧化反应的效率。本工作展示了mof衍生物在室内光催化净化领域的应用前景，也为催化剂改性在光催化降解污染物方面的研究提供了新的视角。

期刊介绍： Applied Catalysis B: Environment and Energy (formerly Applied Catalysis B: Environmental) is a journal that focuses on the transition towards cleaner and more sustainable energy sources. The journal's publications cover a wide range of topics, including: 1.Catalytic elimination of environmental pollutants such as nitrogen oxides, carbon monoxide, sulfur compounds, chlorinated and other organic compounds, and soot emitted from stationary or mobile sources. 2.Basic understanding of catalysts used in environmental pollution abatement, particularly in industrial processes. 3.All aspects of preparation, characterization, activation, deactivation, and regeneration of novel and commercially applicable environmental catalysts. 4.New catalytic routes and processes for the production of clean energy, such as hydrogen generation via catalytic fuel processing, and new catalysts and electrocatalysts for fuel cells. 5.Catalytic reactions that convert wastes into useful products. 6.Clean manufacturing techniques that replace toxic chemicals with environmentally friendly catalysts. 7.Scientific aspects of photocatalytic processes and a basic understanding of photocatalysts as applied to environmental problems. 8.New catalytic combustion technologies and catalysts. 9.New catalytic non-enzymatic transformations of biomass components. The journal is abstracted and indexed in API Abstracts, Research Alert, Chemical Abstracts, Web of Science, Theoretical Chemical Engineering Abstracts, Engineering, Technology & Applied Sciences, and others.
