By combining a CeO2 catalyst with atmospheric carbon dioxide, researchers from Osaka City University, Tohoku University, and Nippon Steel Corporation have developed an effective catalytic process for the direct synthesis of polycarbonate diols without using dehydrating agents. Their method, published in Green Chemistry, does not rely on toxic chemical feedstock like phosgene and carbon monoxide, making it the world’s first high yield “green” reaction system.
