Patent number: 10010866Abstract: The nitrogen and phosphorus co-doped crystalline carbon materials are prepared by a template-free method that includes pyrolizing a precursor mixture including a carbon source, a nitrogen source, and a phosphorus source. The method involves mixing known amounts of the precursor components, dissolving the precursor mixture in deionized water, distilling solvent from the aqueous mixture, and vacuum drying the residue to a dry solid mixture. The mixture is then carbonized by pyrolysis at 900° C. in an argon atmosphere to obtain a nitrogen and phosphorus co-doped crystalline carbon material. The principles of the method are illustrated by a precursor mixture of sucrose, urea, and ammonium dihydrogen phosphate (NH4H2PO4). The amount of ammonium salt in the precursor mixture plays a key role in controlling the crystallinity, morphology, and composition of the N/P co-doped crystalline carbon material.Type: GrantFiled: September 19, 2017Date of Patent: July 3, 2018Assignee: KING SAUD UNIVERSITYInventors: Usman Ali Rana, Arfat Anis, Ayman Nafady, Saeed M.

Patent number: 8147792Abstract: The subject invention provides a potentially economically viable method for the preparation of reactive superoxide ion in deep eutectic solvents (DES). The superoxide ion can be used for many applications, e.g. the degradation of hazardous chemicals at ambient conditions or in the synthesis of some special chemicals, e.g. carboxylic acids, aldehydes, and ketones from the corresponding alcohols. The superoxide ion can be formed by either the electrochemical reduction of oxygen in DES or by dissolving Group 1 (alkali metals) or Group 2 (alkaline earth metals) superoxides, e.g. potassium superoxide, in DES, with/without chemicals used for the enhancement of the solubility of the metal superoxide in the DES, e.g. crown ethers.Type: GrantFiled: March 26, 2008Date of Patent: April 3, 2012Assignee: King Saud UniversityInventors: Inas Muen Al Nashef, Saeed M.

Patent number: 7942972Abstract: A process for separating fructose and glucose from mixtures of fructose and glucose from a liquid phase feed solution or a solid mixture containing the fructose and glucose is disclosed. The process implements ionic liquids as selective solvents that dissolve fructose and glucose in large quantities, but at different proportions which are then separated by filtration into a precipitate and a solution of ionic liquid enriched with the other sugar. The process also involves separation of the sugars from the ionic liquid enriched with the other sugar which is accomplished by one of various processes such as extraction with water in a centrifuge or cooling to reduce the solubility of sugar and then filtration. The ionic liquid is then recycled.Type: GrantFiled: May 13, 2008Date of Patent: May 17, 2011Assignee: King Saud UniversityInventors: Inas M. Al Nashef, Mohamed H. Gaily, Saeed M. Al-Zahrani, Ahmed E.
