Application

  • Carbon Emission Mitigation: Efficient CO2 capture and release for reducing atmospheric carbon levels.
  • Industrial & Agricultural Use: Recycled CO2 can be utilized in various chemical processes and applications.

Description

Researchers at Florida State University developed a novel lignin-based material that efficiently absorbs and releases carbon dioxide (CO2). This material can capture CO2 from both concentrated sources and ambient air, without needing high temperatures or pressure. It can be reused multiple times, making it a sustainable solution for reducing carbon emissions. The process is highly efficient, with CO2 release controlled by adjusting temperature.

Pathway Description:

Lignin is chemically modified through polymerization to create a polymer that can capture CO? from the air or concentrated sources. This polymer absorbs CO? and forms a stable structure. When heat is applied, typically at 60?°C under atmospheric pressure, the CO? is released, allowing the polymer to be reused. The release of CO? can be controlled by adjusting the temperature, enabling the material to be efficiently recycled for repeated use in carbon capture.
