报告题目：Enhanced photocatalytic activity of ZnO nanostructures for water and air purification: from microfluidics to 5th Generation Road
The impact on environment and on human health of different pollutants, especially chemical pollutants, is becoming critical due to their drastic consequences on our main vital resources: water and air. In recent years, extensive efforts of fundamental research and developing practical processes have been devoted to the polluted water & air treatment. The semiconductor-based photocatalytic process has shown a great potential as an environmental-friendly and sustainable treatment technology by using solar energy. Among the photocatalytic materials, nanostructured ZnO is a promising candidate for its high surface/volume ratio, its easy-controllable & low cost synthesis, and its chemical & thermal stability. The ability of ZnO based photocatalysis technology has been widely demonstrated to remove persistent organic compounds (such as dyes, antibiotics, & microorganisms) in water, and toxic gases (such as NOx, COVs, …) in air; and its photocatalytic efficiency can be enhanced by transition metal doping process. ZnO nanostructure is also a promising candidate in microfluidic application for their easy-controllable synthesis and integration in a microfluidic system. ZnO nanostructures can also be synthesized on civil engineering materials for self-cleaning road application to avoid the soil pollution & improve air quality.
