| titleOfInvention | Method for preparing nitrogen-containing titania nano-powder for photocatalysis by utilizing two-emulsions technology |
| abstract | A method for preparing nitrogen-containing titania nano-powder for photocatalysis by utilizing a two-emulsions technology, performed by providing a first emulsion liquid and a second emulsion liquid with alkaline aqueous solution drops and alkaline aqueous solution drops of acetylacetone chelated titanium ions (Ti.sup.4+) as the aqueous phase, respectively. A precursor-containing liquid reaction mixture is formed by mixing two emulsion liquids.. Then, the liquid reaction mixture is distilled so as to remove the oil phase. Finally, the precursors is dried and calcined under an ammonia (NH .sub.3) atmosphere to obtain the nano-scale nitrogen-containing titania (TiO2-xNx) photocatalyst microparticles that shows a property of photocatalysis under the visible light. Since this invention utilizes acetylacetone to chelate titanium ions, particles having better evenness can be formed, and by using experimental designs to determine the optimized process condition, the nano-scale nitrogen-containing titania micropowders having good dispersibility and capable of absorbing the visible light may be obtained. |
