ORNL researchers have developed a process to selectively capture carbon dioxide, sorb it to a catalytic active site, convert it to a product under low temperatures with high efficiency, and desorb from the material to separate it more cost efficiently and at higher purity.
The ability to selectively capture carbon dioxide from a mixed source—air or flue gas, for example—and reductively convert it to a useful fuel or chemical product, while being energy and cost efficient, is difficult.
Current practices are costly, energy intensive, and not always selective for carbon dioxide. Conversion of carbon dioxide is difficult due to its stability and, as a result, it requires a lot of energy to cleave the carbon-oxygen bond, such as though the use of thermal energy, pressures, or an active catalyst. Producing high quality products from the final mixtures is energy intensive or chemically caustic.
A material that can selectively capture carbon dioxide, actively convert it under low energy conditions at low temperature and pressures, and produce a high quality end product is of great value.
ORNL researchers have developed a process to selectively capture carbon dioxide, sorb it to a catalytic active site, convert it under low temperatures with high efficiency, and separate it for end products more cost efficiently and at higher purity.
