TiO2 photocatalytic filters are utilized for various fields of environmental purification, such as decomposition of stench substances and harmful chemicals, etc. However, it turned out that the decomposition rate of sulfide chemicals, such as hydrogen sulfide (H2S) and methylmercaptan (CH3SH), were very slow to react on TiO2 under UV irradiation. In order to improve the decomposition ability of sulfide chemicals, this Ag-deposited Photocatalytic filter has been developed. The Ag-deposited photocatalytic filter was fabricated by coating TiO2 on the porous ceramics body, and successively depositing nano-sized Ag particles on TiO2 by means of photodeposition method. It was observed that Ag deposition on TiO2 improved the adsorption ability for H2S gas and CH3SH gas. Consequently, the Ag-deposited photocatalytic filter could remove H2S gas and CH3SH gas with an 8.0 times, and an 8.7 times effectiveness, respectively, in comparison with conventional TiO2 photocatalytic filter.
