Abstract
A method of hydrogenating carbon dioxide comprises forming a tunable catalyst comprising at least one metal comprising a size within a range of from a single atom to about 999 nanometers and formulated to produce one or more carbon-containing compounds. An electrochemical cell comprising a positive electrode, a negative electrode comprising the tunable catalyst, and an electrolyte between the positive electrode and the negative electrode is formed. Carbon dioxide is introduced to the negative electrode of the electrochemical cell and a potential difference is applied between the positive electrode and the negative electrode to selectively hydrogenate the carbon dioxide. The hydrogen ions are diffused through the electrochemical cell. The carbon dioxide at the negative electrode is hydrogenated to selectively form carbon monoxide, methane, or a desired ratio of carbon monoxide and methane. An electrochemical cell and a carbon dioxide hydrogenation system are also disclosed.
