Researchers trap CO2 from air into nanofibers to prevent its release | The two-step process also produces hydrogen gas as a by-product, which could also be used as a zero-emission fuel.
The researchers found that breaking down the conversion process into stages allowed reactions to happen at lower temperature in presence of different catalysts.
Through their experiments, the researchers recognized that instead of converting CO2 into nanofibers directly, breaking down the process into multiple stages and using different catalysts was far more efficient. Additionally, carbon monoxide (CO) was far more suitable to work with as a starting material, and they now needed a method to generate CO first. To better understand how these reactions take place, the team then used techniques such as X-ray absorption and scattering, Inner Shell Spectroscopy, and electron microscopy to study them.
