Topic: Electrochemical CO₂ Conversion for Sustainable Chemicals, Fuels, and Carbon-Neutral Technologies

The electrochemical conversion of CO₂ has emerged as a promising pathway for producing sustainable chemicals and carbon-neutral fuels, offering a viable strategy to mitigate carbon emissions while enabling high-value chemical manufacturing. In parallel, emerging electrochemical CO₂ capture technologies provide new opportunities to integrate capture and conversion processes, improving overall efficiency and lowering energy demand. Recent advances in catalyst design, reaction engineering, system integration, electrochemical CO₂ capture, and paired electrolysis have significantly accelerated the progress of CO₂ electroreduction toward practical applications. However, challenges still remain in improving selectivity, scaling up reactor performance, reducing energy consumption, and incorporating CO₂ capture–conversion systems into industrial processes.

This Special Issue aims to showcase recent developments that push electrochemical CO₂ capture and conversion from laboratory studies toward real-world implementation. We welcome contributions focusing on catalytic systems, device engineering, mechanistic insights, electrochemical capture strategies, techno-economic analyses, and application-oriented innovations that support sustainable chemical production, low-carbon fuels, and emerging carbon-neutral technologies. Studies that bridge fundamental understanding with practical deployment are particularly encouraged.

This Special Issue seeks original research articles, reviews, perspectives, and communications from researchers working across electrochemistry, materials science, energy engineering, catalysis, and carbon utilization technologies.
