Carbon-doped catalysts help turn CO2 gas into fuels and chemicals
For the first time in human history, CO2 levels in the atmosphere exceeded 415.26 parts per million in 2019, according to sensors at the Mauna Loa Observatory in Hawaii. The electrochemical reduction of CO2 provides a potential route to removing this harmful gas from the atmosphere. The EU-funded DimerCat project will investigate carbon catalysts doped with metal dimers for the efficient conversion of CO2 into chemicals and carbon-based fuels. Carbon-based catalysts are chosen for their high selectivity towards CO formation, while the doped metal dimers are expected to favour the CO–CO coupling, leading to the formation of C2 products such as ethene. Apart from catalyst design, the project aims to overcome two other major challenges related to catalysts: their selectivity and large-scale production.
