Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
We claim: 1. A method of making an electrocatalyst for electrochemical conversion of carbon dioxide, comprising the steps of: dissolving copper nitrate trihydrate in deionized water to form a salt solution; adding titania nanotubes to the salt solution to form a suspension; heating the suspension; adding a urea solution to the suspension to form an electrocatalyst in solution, the electrocatalyst being copper material supported on the titania nanotubes; and removing the el…
