Patent number: 9109293Abstract: An electrocatalyst for the electrochemical conversion of carbon dioxide to hydrocarbons is provided. The electrocatalyst for the electrochemical conversion of carbon dioxide includes copper material supported on carbon nanotubes. The copper material may be pure copper, copper and ruthenium, copper and iron, or copper and palladium supported on the carbon nanotubes. The electrocatalyst is prepared by dissolving copper nitrate trihydrate in deionized water to form a salt solution. Carbon nanotubes are then added to the salt solution to form a suspension, which is then heated. A urea solution is added to the suspension to form the electrocatalyst in solution. The electrocatalyst is then removed from the solution. In addition to dissolving the copper nitrate trihydrate in the deionized water, either iron nitrate monohydrate, ruthenium chloride or palladium chloride may also be dissolved in the deionized water to form the salt solution.Type: GrantFiled: July 25, 2014Date of Patent: August 18, 2015Assignees: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALS, KING ABDULAZIZ CITY FOR SCIENCE AND TECHNOLOGYInventors: Saleem Ur Rahman, Syed Mohammed Javaid Zaidi, Shakeel Ahmed, Sk Safdar Hossain

Patent number: 9099752Abstract: The electrocatalyst for the electrochemical conversion of carbon dioxide includes a copper material supported on titania nanotubes. The copper material may be pure copper, copper and ruthenium, or copper and iron supported on the titania nanotubes. The electrocatalyst is prepared by first dissolving copper nitrate trihydrate in deionized water to form a salt solution. Titania nanotubes are then added to the salt solution to form a suspension, which is then heated. A urea solution is added to the suspension to form the electrocatalyst in solution. The electrocatalyst is then removed from the solution. In addition to dissolving the copper nitrate trihydrate in the volume of deionized water, either iron nitrate monohydrate or ruthenium chloride may also be dissolved in the deionized water to form the salt solution.Type: GrantFiled: July 24, 2014Date of Patent: August 4, 2015Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Saleem Ur Rahman, Syed Mohammed Javaid Zaidi, Shakeel Ahmed, Sk Safdar Hossain
