Panasonic Corporation Details Findings in Combinatorics (Systematic Analysis of Electrochemical CO2 Reduction with Various Reaction Parameters using Combinatorial Reactors)
By a News Reporter-Staff News Editor at Journal of Mathematics -- Investigators discuss new findings in Combinatorics. According to news reporting originating from Kyoto, Japan, by VerticalNews correspondents, research stated, "Applying combinatorial technology to electrochemical CO2, reduction offers a broad range of possibilities for optimizing the reaction conditions. In this work, the CO2 pressure, stirring speed, and reaction temperature were varied to investigate the effect on the rate of CO2 supply to copper electrode and the associated effects on reaction products, including CH4."
Our news editors obtained a quote from the research from Panasonic Corporation, "Experiments were performed in a 0.5 M KCl solution using a combinatorial screening reactor system consisting of eight identical, automatically controlled reactors. Increasing the CO2 pressure and stirring speed, or decreasing the temperature, steadily suppressed H-2 production and increased the production of other reaction products including CH4 across a broad range of current densities. Our analysis shows that the CO2 pressure, stirring speed, and reaction temperature independently contributed to the limiting rate of CO2 supply to the electrode (j(lim)). At a constant temperature, the limiting current density of CH4 increased proportionally with J(lim), illustrating that the production rate of CH4 was proportional to CO2 supply. Varying the CO2 pressure and stirring speed hardly affected the maximum Faradaic efficiency of CH4 production. However, changes to the reaction temperature showed a significant contribution to CH4 selectivity."
According to the news editors, the research concluded: "This study highlights the importance of quantitative analysis of CO2 supply in clarifying the role of various reaction parameters and understanding more comprehensively the selectivity and reaction rate of electrochemical CO, reduction."
