Singapore researchers first to transform carbon dioxide into methanol

Scientists at Singapore’s Institute of Bioengineering and Nanotechnology (IBN) have succeeded in unlocking the potential of carbon dioxide

Organocatalysts are catalysts that are comprised of non-metallic elements found in organic compounds. NHCs such as IMes (1,3-bis-(2,4,6 trimethylphenyl)imidazolylidene) are a form of organocatalysts that are stable and easily stored. They do not contain toxic heavy metals and can be produced easily without high costs.

The IBN scientists showed that only a small amount of NHC is required to induce carbon dioxide activity in a reaction. “NHCs have shown tremendous potential for activating and fixing carbon dioxide. Our work can contribute towards transforming excess carbon dioxide in the environment into useful products such as methanol,” said Siti Nurhanna Riduan…

…Previous attempts to reduce carbon dioxide to more useful products have required more energy input and a much longer reaction time. They also require transition metal catalysts, which are both unstable in oxygen and expensive. Ongoing research at IBN aims to find cheap alternatives for the hydrosilane reagent so that the production of methanol can be even more cost-effective for mass industrial production.
