The Research of the Performance of Active Carbon Loaded Nano-Sized TiO2 in Formaldehyde Decontamination in Fluidized Bed Reactor

TiO2/active carbon (AC) photo catalysts are prepared by sol-gel method. We have designed a fluidized bed reactor to decontaminate the formaldehyde. In our experiment, active carbon and TiO2/AC are used as the air purification materials in the reactor. Flat aluminum sheets and electric field are introduced into the reactor. Our result shows that TiO2/AC materials have high removal rate, and it can reach 80%. When we add flat sheets and stable electric field, the removal rate reach over 90%.
