Evaluation of Photocatalytic Abilities by Variation of Conductivity and Dimethyl Sulfoxide: Photocatalytically Active TiO₂-coated Wire Mesh Prepared via a Double-layer Coating Method

抄録

Herein, we evaluated the quality of a double-layer coating method to stably immobilize photocatalysts by photodecomposition of dimethyl sulfoxide (DMSO) on a stainless-steel wire mesh using a flow analytical system, which included the reactor and conductimetric detector (FAS-CD). The prepared photocatalyst consisted of an amorphous titanium peroxide sol layer and a layer of a sol mixture containing TiO₂ and amorphous titanium peroxide. Stable photocatalytic activity was demonstrated through successive photodecomposition tests of DMSO using FAS-CD/equipment.
