Electrochemical CO 2 reduction (CO 2 R) provides a sustainable route to produce the fuels and industrially relevant chemicals that society depends upon. While these products are generally fossil fuel derived, renewable energy (i.e., wind, solar, hydro) can be coupled with CO 2 R to achieve a carbon-neutral artificial photosynthesis process.

Boosting the Efficiency of Electrochemical Carbon

Stephens adds, "Carbon dioxide reduction has a great potential as a way of making platform chemicals, such as ethylene, from waste electricity, water, and carbon dioxide. Ethylene is currently formed by cracking long chain hydrocarbons from fossil fuels; its production emits copious amounts of carbon dioxide to the atmosphere.
