Invention Reference Number
This technology overcomes the limitations of carbon materials like Carbon Nanotubes (CNT) and graphene in carbon dioxide reduction. These materials show significant inactivity in electrochemical carbon dioxide (Na-CO2)reduction applications. This technology is a unique solution focusing on enhancing the efficacy of sodium-carbon dioxide (Na-CO2) batteries. It uses a specialized treatment process applied to carbonaceous materials. The result is much improved efficiency and effectiveness of next generation metal-CO2 batteries.
Description
Traditionally, enhancing carbon dioxide reduction efficiency involves laborious and time-consuming methods, such as coating with ruthenium metallic catalysts or organic solvent processing at elevated temperature. However, these methods are costly and challenging to scale for broader applications. This technology introduces a novel, cost-effective, and scalable method that significantly enhances carbon dioxide reduction capabilities of these carbon materials for use in Na-CO2 batteries. The technology subjects these materials to nitrogen plasma treatment that plays a crucial role in activating the carbonaceous materials, thereby making them more efficient for the carbon dioxide reduction reaction process. By altering the surface properties and electronic structure of the carbonaceous materials through nitrogen plasma treatment, their catalytic activity is enhanced, particularly for CO2 reduction. This increases efficiency and effectiveness of Na-CO2 batteries for the next generation of high-performance batteries.
