Electrochemical Transformation of CO2 to Value-Added Chemicals and Fuels

Abstract

CO2 is the main greenhouse gas and a renewable carbon resource. Electrochemical transformation of CO2 (CO2ET) to value-added chemicals and fuels is one of the promising routes to reduce CO2 emission and contributes to sustainability and carbon neutrality. In this review, we discuss recent developments on apparatuses used in CO2ET, electrocatalytic reactions of CO2 with water, organics, nitrogen, and nitrogen-containing compounds to synthesize chemicals and fuels by the construction of different chemical bonds (e.g., C-H, C-C, C-O, and C-N), and related reaction mechanisms. Also, an outlook was considered to highlight the opportunities and challenges in CO2ET.
