摘要

Environmental chemical pollution in water and air is induced by increasing human activity such as industry, transportation, intensive agriculture and growing urbanization. These global environmental issues are now listed among the sustainable development goals (SDGs), hence the increasing scientific and technological interests on water depollution and air purification, besides the needs for selective measurement of pollutants. ZnO nanostructures have been widely studied as a very promising material to rise such challenge of depollution/purification. Online monitoring of air purification is presented, where purification is made by photo-catalysis using ZnO nanowires, while monitoring is achieved by a MEMS-FTIR spectrometer operating in the mid-infrared MIR spectral range. The experiment was conducted on toluene, acetone as well as tobacco smoke. The whole system appears as an efficient and cheap solution for indoor and outdoor purification and monitoring of air.
