Chinese and Canadian researchers make headway on intermediates from CO2

In China, a research team led from University of Science and Technology of China and the University of Toronto has uncovered a catalysis strategy producing intermediates during CO₂ electrochemical reduction reaction, which sheds new lights on upgrading CO₂ to engine fuels.

When it comes to designing catalysts for CO₂ conversion, many researches on the C-C coupling step have been done; while little attention has been paid to post-C-C coupling reaction.

By deliberately incorporating sulfur atoms into the catalyst core and copper vacancies in its shell, researchers realized Cu₂S-Cu-V core-shell nanoparticles that enhance CO₂ reduction to ethanol and propanol. Structural characterization, x-ray studies, and electrochemical measurements were utilized to illustrate how good this new catalyst is in improving catalytic performance.

This discovery will inspire the design of efficient catalysts that produce higher-carbon liquid alcohols. In addition to address the need for long-term storage of renewable electricity and decarbonization of the transportation sector via electrocatalytic reduction of CO₂ to chemical feedstocks. And the results were published in Nature Catalysis on Jun 11th.
