Creating compounds that filter CO2 and turn them into materials for bottles and clothes

Human's fight against climate change has one more good news. Material chemist Ken-ichi Otake of Kyoto University, Japan, and his colleagues have recently created a compound that can attract CO ₂ molecules in the air and turn them into organic matter. muscles are capable of making materials for bottles or everyday wear.

This compound is recyclable for reuse and still works effectively after 10 times of recycling.

This potential compound is a porous coordination polymer (PCP) made of zinc ions. These ions can hold CO ₂ molecules 10 times more efficiently than other polymers. This compound is even recyclable for reuse, and still works effectively after 10 times of recycling.

The idea of ​​converting CO2 in the atmosphere into beneficial compounds, reducing the harmful effects of climate change, is actually not new anymore. But using a PCP (also known as an organic metal frame - MOF) has a higher potential than many other ways of converting CO ₂ . The reason is that they can be recycled to further filter CO ₂ , or processed to become polyurethane, which can be used in clothing, packaging, consumer goods and many other applications. The organic metal frame, exactly as its name implies, identifies substances based on molecular shapes accurately. As a result, it only absorbs CO ₂ molecules, not other molecules in the air.

Previously, scientists at RMIT Australia created a way to turn CO ₂ into coal, using a metal-based chemical called Cerium to create a reaction. A team of other scientists at Rice University in the United States created a device to turn CO ₂ into a liquid fuel, using the Bismuth metal as its main ingredient.
