| titleOfInvention | Process for synthesizing nano-powdered sols of visible light responsive TiO2 |
| abstract | The present invention provides a manufacturing process for nano-powdered sols of TiO2, which is responsive to visible light, utilizing titanium compound, such as titanium tetrachloride or titanium sulfate. After dilution, ammonium water is used to adjust pH to 7.0-9.0, generating titanium hydroxide. After washing and filtering, appropriate oxidant or acid (including inorganic acid and organic acid) or both, additive, modifier and surfactant (if necessary) are added. Depending on operating conditions, nano-powdered sols of TiO2, which is responsive to visible light, are synthesized, having visible light-responsively photocatalytic property. The products are processed and applied to the surface of object being handled. After baking and drying, the surface of object being handled forms a thin layer with good adsorption, having photocatalytic or self-cleaning property while illuminating by visible light. The products of this invention can appear colorless to golden yellow or yellowish brown sols liquid depending on the type and concentration of additives and also operating conditions thereof. The content of TiO2 ranges from 0.5~10% (depending on conditions), and the particle size of nano-powered TiO2 is varied depending on operating conditions. Those nano-powdered particles ranging from 2~50 nm in size possess photocatalytic force and multiple efficacy, such as self-cleaning, easy-to-clean, hard-to-pollute, anti-mold, deodorization and fog-resistance. |
