Researchers Have Designed a Material That Transforming CO2 Into Useful Natural Polymer

Researchers have come up with a ground-breaking approach to try and curb the immense measures of carbon dioxide we’re still pumping into the air, even as a climate crisis unfurls around us: transforming that CO2 into a useful natural polymer.

The innovative approach drains CO2 molecules out of the atmosphere, without using a lot of energy all the while. The material can then possibly be transformed into an element for clothing or packaging. The secret weapon from the arsenal is a porous coordination polymer (PCP) made up of zinc metal particles. Those particles can specifically suck CO2 molecules with 10 times more proficiency than different PCPs, the scientists state. Likewise, the material is reusable and was still running at maximum productivity after 10 reaction cycles.

“We have effectively designed a porous material which has a high affinity towards CO2 atoms and can rapidly and successfully convert it into useful organic materials,” says materials chemist Ken-ichi Otake, from Kyoto University in Japan.

The possibility of carbon sequestration has been around for quite a while; however, the low reactivity of carbon dioxide implies it’s hard to capture and lock away without using a lot of energy en route – which sort of nullifies the purpose.

PCPs (otherwise called metal-organic frameworks or MOFs) may hold the key to beating this obstacle. The one delineated in this new study uses a clever trick: an organic component with a propeller-like structure.

Using X-ray structural analysis, the scientists found that as CO2 particles approach the PCP, its sub-atomic structure rotates and rearranges, allowing the carbon dioxide to be caught in the material.

The PCP is basically working as an atomic sieve, ready to perceive particles by size and shape. When the material has done its CO2-sucking work, it very well may be reused or reused as an organic polymer. Organic polymers can be transformed into polyurethane, which is used in clothing, packaging, domestic appliances, and an assortment of different regions. We see various promising in the field of carbon storage. Prior this year, researchers from RMIT University in Australia presented an approach for transforming CO2 back into coal, using a chemical reaction involving the metal cerium.

Another group of researchers from Rice University in the US has had the option to develop a device for transforming CO2 into liquid fuel: for this situation, the metal bismuth is the key ingredient, and formic acid is the final product.

Every one of these ideas require further research and need to work at larger scales; however, progress is being made. All things considered, they shouldn’t occupy us from the ideal method of cutting down the CO2 in the atmosphere and showing global warming – reducing our carbon emissions.

It’s clear that action needs to be taken and fast. This new CO2 conversion method may well become very important to us later on, not least since it transforms something we don’t need into something we do.

“Perhaps the greenest ways to capture CO2 is to recycle it into high-value chemicals, for example, cyclic carbonates which can be used in petrochemicals and pharmaceuticals,” says materials chemist Susumu Kitagawa, from Kyoto University.
