Chemists improve electrochemical production of sustainable chemical building blocks

Researchers Isolate and Characterize Elusive Intermediate in Water Oxidation Reaction

Alkali cations boost carbon dioxide reduction into feedstock chemical

By Fernando Gomollón-Bel2021-05-06T13:30:00+01:00 Source: © Angelika Samu/University of Szeged The flow chemistry apparatus developed by researchers at the University of Szeged in Hungary can reduce carbon dioxide more efficiently than other methods Electrochemical reduction of carbon dioxide is an attractive solution to combat climate change. Now, researchers at the University of Szeged, in Hungary, have discovered an integrated solution to tackle this reaction in continuous flow, overcoming long-term stability problems and enabling a scalable process. Using electricity to valorise carbon dioxide has fulfilled a dual purpose. It decreases emissions and, at the same time, offers the chemical industry an alternative carbon source to manufacture valuable raw chemicals, such as carbon monoxide, formic acid and methanol. However, several hurdles have blocked the adoption of these technologies. Among other things, it requires a very basic reaction environment, which contributes to

Producing Biobased Polyesters with Tunable Properties

Producing Biobased Polyesters with Tunable Properties Written by AZoMMar 3 2021 As far as green chemistry is concerned, identifying novel and lasting solutions to the material needs is one of the main targets.

The countless plastics used by people in their everyday life, right from mattresses to food and cars, are mainly made from oil-based monomers that form the building blocks of polymers. Determining bio-based monomers for polymer synthesis is an appealing way to realize more lasting solutions in the area of materials development. In a study published in the ACS Sustainable Chemistry & Engineering journal, scientists from the Kleij group describe a new method to make biobased polyesters with tunable properties. The team has been developing the multifunctional structure of the terpene β-elemene: three double bonds that exhibit unique reactivity, thus enabling a selective transformation of such bonds and h
