The electrochemical reduction of carbon dioxide (CO2R) is a key technology to combat global climate issues. By utilizing renewable energy, we can convert greenhouse gases into value-added commodity chemicals. While there has been a growing number of CO2R research in recent years, there are still many unanswered fundamental questions and engineering challenges. On a fundamental level, we would like to rationally design affordable and stable materials to control the reaction pathway to selectively produce C2 and C3 products and understand the electrolyte ion effects at the electrochemical interface. On a practical system level, we need to reduce carbonate formation and mass transport limitations, lower the operating cell voltage, improve CO2 utilization and energy efficiencies, and incorporate real world CO2 streams containing SOx/NOx.
With this collection, we encourage scientists from different academic backgrounds to explore these remaining challenges in the CO2 electrochemical reduction reaction and provide a forum for the CO2 community to share their latest research results. Topics of interest include, but are not limited to, the following:
Heterogeneous or homogeneous catalytic materials
Computational theory, including DFT and finite element modeling
Electrochemical interfaces and the electrolyte effects
In situ spectroscopic and electroanalytical methods for mechanistic investigations
System engineering for electrolyzer configurations
Technoeconomic analyses of practical CO2 electrolyzer systems
We welcome all submission of original research articles, reviews and perspectives related to the theme of CO2 electrocatalytic reduction.
