报告摘要

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.
