Currently, 21% of the global greenhouse gas emissions come from the industry sector, while chemical manufacturing accounts for the largest share of industrial carbon emissions. Electrochemical processes, powered by renewable energy, present a sustainable alternative to the conventional thermochemical methodologies that depend on fossil fuels. With the swift advancement of renewable electricity, the electrification of chemical production emerges as a promising solution for the decarbonization of the chemical industry.1

This presentation will discuss the electrochemical processes aimed at the production of chemicals traditionally associated with high emission footprints. I will begin with the design of high-performance CO2 electrolysis systems that transform CO2 and water into valuable chemicals and fuels. A particular focus will be on how the integration of tandem electrocatalytic and electrocatalytic-thermocatalytic systems enhances Faradaic efficiency and carbon efficiency in CO2 conversion.2-3

Furthermore, I will discuss the electrochemical processes for synthesizing high-carbon-footprint chemicals, such as ethylamine, ethylene glycol, and nitric acid.4-5 The presentation will highlight how the fusion of cutting-edge catalyst design, operando spectroscopy for real-time characterization, and the engineering of electrochemical reactors, combined with techno-economic analysis and life cycle assessment, can bridge the gap between fundamental research and practical applications. This approach is aimed at making electrochemical processes a feasible and scalable option for decarbonizing the chemical industry.
