报告简介：Chemical pollution in water and air induced by increasing human activity is a growing threat to our planet. This is why one of the goals of sustainable development is water depollution and air purification. The ZnO nanostructure is a very promising material to rise to such challenge. Indeed, the photocatalysis is a well-known and efficient process for achieving water & air depollution, with very limited rejects in the environment. As an excellent photocatalyst, ZnO is able to mineralize a large scale of organic pollutants in water & air. The main obstacles for using ZnO as a photocatalyst are the high recombination rate of photo-generated electron/hole pairs, and its wide band-gap, which only allows the use of photons from UV spectrum in photocatalytic process. In this work, the doped ZnO nanowire were synthesized by a simple two-step hydrothermal method, and their high photocatalysis performance has been demonstrated for the degradation of some largely widespread industrial dyes, as well as for the COVs depollution.
