Abstract Electrochemical processes coupling carbon dioxide reduction reactions with organic oxidation reactions are promising techniques for producing clean chemicals and utilizing renewable energy. However, assessments of the economics of the coupling technology remain questionable due to diverse product combinations and significant process design variability. Here, we report a technoeconomic analysis of electrochemical carbon dioxide reduction reaction–organic oxidation reaction coproduction v

The severe increase in the CO2 concentration is a causative factor of global warming, which accelerates the destruction of ecosystems. The massive utilization of CO2 for value-added chemical production is a key to commercialization to guarantee both economic feasibility and negative carbon emission. Although the electrochemical reduction of CO2 is one of the most promising technologies, there are remaining challenges for large-scale production. Herein, an overview of these limitations is provide

A catholyte-free membrane electrode assembly (MEA) has been proposed for practical application in the electrochemical CO2 reduction reaction (eCO2RR), and water management becomes critical in its catalyst–membrane interface. We investigate roles of the water supply within the MEA for ethylene production by utilizing deuterium-labeled water. The protons of ethylene originated mainly from the anolyte not the humidified water through the cathode, indicating that dominant water flux from the anolyte

Discovering new materials better suited to specific purposes is an important issue in improving the quality of human life. Here, a neural network that creates molecules that meet some desired multiple target conditions based on a deep understanding of chemical language is proposed (generative chemical Transformer, GCT). The attention mechanism in GCT allows a deeper understanding of molecular structures beyond the limitations of chemical language itself which cause semantic discontinuity by payi

The activity and selectivity for C 2+ products from electrochemical CO 2 reduction in a zero-gap membrane-electrode assembly (MEA) are improved using a synchronous KOH-activation and tailoring of Cu catalyst thickness.

The assessment highlights the promise that direct electrochemical conversion of captured CO 2 technology has the potential to be an economically and environmentally effective alternative to the current energy-demanding CO 2 capture and utilization systems.
