Xúc tác quang micro nanocompozit trên cơ sở TiO2 – nanocacbon mang trên vật liệu đệm cacbon có cấu trúc

Abstract

Composite TiO₂/Carbon nano­ based photocatalysts are being investigated abundantly in the world because of their high photoactivity and their capacity in absorbing almost of sun­s irradiation. By absorbing a photon, these catalysts can promote the total oxidation of organic compounds to CO₂, H₂O products. However, researches about this ­composite­ are just for a the powder catalysts applications in a batch reactor. Their uses in the continuous system seem impossible. In Vietnam, these catalysts are completely untouched. Therefore, our researches are now focused onto the new photocatalysts based on ­composite TiO₂ commercial, sol-gel/carbon nano­ with macroscopic shaping. This new type of catalyst allows amplifying the photoactivity and reducing the cost. These catalysts were successfully applied in our laboratory for continuous systems to degradate organic compounds in waste water.
