Photocatalytic Properties of TiO2 According to Manufacturing Method

초록

TiO2 photocatalyst powders were prepared by chlorination method and sol-gel method. Specific surface area and crystalline (i.e., anatase and rutile) of the catalyst varied depending on manufacture conditions and method. TTIP-sol photocatalyst had higher methylene blue (MB) decomposition characteristics than photocatalyst from chlorination method and TBOT-sol. MB removal efficiency from aqueous solution with TTIP-sol photocatalyst was over 90%. Experimental results showed that the TiO2 photocatalyst with a single anatase phase and a large specific surface area had high decomposition characteristics of organic materials.
