TITANIUM OXIDE XEROGEL FILMS IN POROUS ALUMINA FOR PHOTOCATALYTIC APPLICATION
Titanium dioxide has been synthesized by a sol-gel method in pores of a membrane from porous anodic alumina. The samples were used in a test reaction of the degradation of organic dye, rhodamine B. The rhodamine B concentration was estimated based on the changes in the 554 nm region of absorption spectra of an organic dye-containing aqueous solution exposed to a mercury lamp emission. The synthesized titanium oxide xerogel in the porous anodic alumina membrane can be used as an effective photocatalyst for the decomposition of organic dyes in an aqueous medium.
