MnO₂ 촉매 합성과 섬유 기반 필터 적용을 통한 상온 포름알데히드 산화 성능 연구 = A Research on the Room-Temperature Formaldehyde Oxidation Performance through MnO₂ Catalyst Synthesis and Fiber-Based Filter Application

다국어 초록 (Multilingual Abstract)

As the long-term exposure to VOCs in indoor air continues to raise concerns about human health risks, the development of catalytic oxidation technology that can operate at room temperature without an external energy supply has emerged as a critical task. In this study, we synthesized a MnO₂ catalyst and fabricated a catalytic filter by directly growing it on the surface of a fiber-based filter through a coating process. The fabricated catalytic filter exhibited excellent structural stability and catalytic activity due to the uniform distribution of the catalyst across the entire fiber surface. In the static experiment, over 86% of HCHO was removed, and approximately 85% of CO₂ was produced during the oxidation process. Additionally, in the dynamic experiment, an HCHO removal efficiency of approximately 89% was shown. This suggests that the room-temperature oxidation reaction by reactive oxygen species on the catalyst surface was effective. Therefore, this catalytic filter can be applied as an effective room-temperature-operated catalytic filter in an indoor air quality improvement system.
