Carbon dioxide cycle via electrocatalysis: Electrochemical carboxylation of CO2 and decarboxylative functionalization of carboxylic acids

As one of the most important biogeochemical cycles, the carbon dioxide (CO2) cycle between atmosphere and biosphere has a profound impact on the life on earth. Therefore, the search for sustainable solutions to normalize the currently unbalanced carbon dioxide cycle is the central research topic of many scientific disciplines. The green and sustainable electrocatalysis offers a very promising answer to currently unbalanced carbon dioxide cycle. In this review, recent advances in electrocatalysis enabled CO2 cycle including the electrochemical carboxylation of CO2 and decarboxylative functionalization of carboxylic acids are highlighted.
