A metal-free electrocatalyst for carbon dioxide reduction to multi-carbon hydrocarbons and oxygenates

Abstract

Electroreduction of CO2 into C2 hydrocarbons and liquid fuels is a promising but challenging energy conversion technology, with copper exhibiting fair selectivity for these products. Here, the authors report that N-doped graphene quantum dots can also catalyze the electrochemical reduction of CO2into multi-carbon hydrocarbons and oxygenates.
