Novel Photocatalyst and Photocatalytic Reactor For Degradation Of 4-Chlorophenol In Wastewater

摘要

A new TiO-2 photocatalyst immobilized on active carbon, was made by sol-gel technique. The average diameter of TiO-2 catalysts was 50-100nm. The new photocatalysts had higher specific surface area, floating, and photocatalytic activity. A novel fluidized bed photoreactor was designed and established. It is a typical trpical triphasic photoreactor. the photocatalytic degradation of 4-chlorophenol in wastewater was studied in the fluidized bed photoreactor. Results showed that the reactor and catalysts were efficient for the degradation of 4-chlorophenol in wastewater.
