Researchers at Tokyo Institute of Technology have refined a rhenium-based catalyst which works with triethanolamine to reduce low concentrations of CO2 from flue gases. Decades of work on the catalyst has culminated in the new method, which is capable of reducing carbon dioxide even when concentrations are only 1% by volume in a gas mixture, making it especially interesting for industries such as fossil fuel-fired power generation, cement and steel making, and other CO2 intensive processes. Most of the CO2 is reduced to CO, a gas that is more easily used as a feedstock for chemical processes. The research has been published in Chemical Science.
