New material captures CO2

Researchers at the University of Nottingham (UK) are developing a new spongy material called the NOTT-202a that is capable of absorbing CO ₂ , marking a significant step forward in the creation of new, bon, contribute to reducing emissions from the activities fossil fuel combustion.

The NOTT-202a consists of a honeycomb-shaped 4-COOH combination formed by a molecular chain or i-on attached to a central metal atom, creating a new structure consisting of two knit frames together.

The structure of this material allows it to absorb various gases such as nitrogen (N ₂ ), methane (CH ₄ ), hydrogen (H ₂ ), or carbon dioxide (CO ₂ ). However, under low pressure, only CO ₂ is retained, while other gases are released.

A team led by Professor Martin Schröder is currently working to improve the selective absorption of the NOTT-202a material before it is put into practical use.

The big problem that the team is facing is the cost of some of the ingredients that make up the material is not cheap, especially in-going metal. In the context of the human race's tendency to produce cheap or reusable CO ₂ capture materials, the application of the NOTT-202a at current cost seems to have to be considered. again.
