Abstract: Processes and apparatus for electrocatalytically converting carbon dioxide emissions and/or ambient carbon dioxide into useful chemicals are described. The process may include: removing carbon dioxide from ambient air through a carbon capture technique, supplying a carbonate or bicarbonate aqueous solution as cathode feed to a cathode of an electrolytic cell comprising a membrane electrode assembly which includes a bipolar membrane separating an anode from the cathode, and applying an electrical potential difference between the cathode and the anode of the membrane electrode assembly to electrocatalytically reduce the carbonate or bicarbonate aqueous solution to carbon monoxide or another useful chemical.

Abstract: An electrochemical device and method can include techniques involving bipolar membrane electrolysis to transform an input product into an output product. Some embodiments can include a gas-diffusion electrode as a cathode, a bipolar membrane configured to facilitate autodissociation, and an anode that can be configured as a liquid-electrolyte style electrode or a gas-diffusion electrode. In some embodiments the electrochemical device can be configured as a CO2 electrolyzer that is designed to utilize input product including carbon dioxide gas and water to generate output products that can include gaseous carbon monoxide or other reduction products of carbon dioxide and gaseous oxygen or the oxidation products of a depolarizer such as hydrogen, methane, or methanol. Embodiments can be utilized in the production of fuels or feedstocks for fuels and carbon-containing chemicals, in air purification systems, flue gas treatment devices, and other machines and facilities.

Abstract: The present invention provides a method for making materials and electrocatalytic materials comprising amorphous metals or metal oxides. This method provides a scalable preparative approach for accessing state-of-the-art electrocatalyst films, as demonstrated herein for the electrolysis of water, and extends the scope of usable substrates to include those that are non-conducting and/or three-dimensional electrodes.
