Patent number: 9126146Abstract: A photocatalyst is provided that comprises activated carbon produced from date pits, impregnated with TiO2. The activated carbon can have a porous surface that can attract and trap pollutants flowing in air or water. The photocatalyst can be made by a method that includes preparing activated carbon by calcining date pits to form a precursor material, and then impregnating the precursor material with titanium dioxide.Type: GrantFiled: January 16, 2012Date of Patent: September 8, 2015Assignee: The National Titanium Dioxide Co. Ltd. (CRISTAL)Inventors: Yousef Saleh Al-Zeghayer, Sami M. Bashir, Ahmed V. Yaser, Hassan M. El Dekki, Waheed A. Al-Masry, Fadi M. Trabzuni

Patent number: 9028913Abstract: A method of preparing coated titanium dioxide particles is provided. The method can include forming an aqueous suspension of titanium dioxide particles having a pH of from about 5.0 to about 7.0; adding a zirconium oxide-forming solution to the suspension in an amount sufficient to decrease the pH of the suspension to about 4.0 or lower; forming a zirconium oxide coating on the titanium dioxide particles to form a suspension of coated particles; adding an aluminum oxide-forming solution to the suspension of coated particles in an amount sufficient to increase the pH of the suspension to about 9.0 or higher; and forming an aluminum oxide coating on the coated particles to form a product.Type: GrantFiled: October 1, 2007Date of Patent: May 12, 2015Assignee: The National Titanium Dioxide, Co. Ltd. (CRISTAL)Inventors: Sami M. Bashir, Fadi Mohammed Saeed Trabzuni, Ahmed V. Yaser
