(599d) Advancements in Electrochemical Methane Conversion: A Pathway to Enhanced Efficiency and Sustainability

The efficient conversion of methane into alcohols remains a pressing challenge with significant implications for resource optimization and environmental sustainability. Traditional, energy-intensive synthesis routes impose considerable limitations. Recently, electrochemical conversion has gained attention as a promising alternative due to its capability for direct partial oxidation of methane even under ambient temperature conditions. Here, we present our recent findings aimed at resolving these issues in electrochemical methane conversion. First, we introduce a methane-to-ethanol electrochemical conversion approach using an ionic oxidant, demonstrating a viable reaction energy pathway through combined experimental and computational methods. Second, we explain how a nanorod-structured catalyst enhances electrochemical methane conversion efficiency. Third, we present a novel concept of electrochemical methane conversion coupled with water splitting. Lastly, we discuss our investigation of a scalable and continuous reaction system.
