Abstract

TiO$_2$ photocatalyst films deposited beads were prepared by circulating fluidized bed chemical vapor deposition(CFB-CVD) using TTIP(Titanium Tetra Iso-Propoxyde). Photocatalytic activities of Photocatalyst beads were evaluated by decomposition rate of formaldehyde in aqueous solution using a photo-reactor. From the result of photocatalytic degradation of formaldehyde, decomposition rate were shown gradually increased according to the increase of UV intensity, circulating fluid velocity and addition amount of H$_2$O$_2$. However the decomposition rate of formaldehyde were decreased according to the increase of initial concentration and pH value.
