Scientists Develop Method to Convert CO2 into Carbon Nanofibers

Overview

• Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory and Columbia University have developed a method to convert carbon dioxide (CO2) into carbon nanofibers, a material with unique properties and potential long-term uses.
• The process uses tandem electrochemical and thermochemical reactions run at relatively low temperatures and ambient pressure, which could successfully lock carbon away in a useful solid form to offset or even achieve negative carbon emissions.
• The carbon nanofibers can be used to strengthen building materials such as cement, locking the carbon away in concrete for at least 50 years, potentially longer.
• The process also produces hydrogen gas (H2), a promising alternative fuel that, when used, creates zero emissions.
• The catalysts used in the process are commercially available and can be recycled, making the process energy-efficient and cost-effective.
