室内甲醛污染控制技术研究进展

Development in pollution control technology of indoor formaldehyde

综述了吸附法、植物净化法、空气负离子技术、化学反应法、光催化法以及热催化氧化法等室内甲醛污染控制技术。其中,热催化氧化法尤其是室温催化氧化法在不用外加光源和热源情况下即可催化甲醛完全氧化,便于集成到空气净化器或通风空调系统中,适用范围广,被认为是空气净化技术发展的趋势,具有广阔的发展空间和应用前景。催化剂作为室温催化氧化技术的核心,开发高效稳定、廉价易得的室温应用催化剂将成为室内甲醛污染控制技术的重点研究方向。

The control technologies of the indoor formaldehyde pollution such as adsorption, plants purifi- cation, negative air ions technology, chemical reaction, photocatalysis and thermal catalytic oxidation （TCO） were reviewed. Among these technologies, TCO and especially the room temperature catalytic oxidation techniques could achieve formaldehyde complete oxidation at ambient temperature and without any additive light or heat sources. They were convenient to be integrated into air purifiers or ventilation and air conditioning systems and had wide application range. Therefore, these approaches are considered as the trend of air purification technologies, and have the wide developing space and great application prospect. Since the catalyst is the core of the room temperature catalytic oxidation approach, it will become one of the most important research directions to develop highly efficient, extremely stable, low-cost and ease-to-obtained catalysts in the indoor formaldehyde pollution control technologies.
