A groundbreaking development in ammonia synthesis has emerged from the State University of New York at Buffalo, where researchers have devised a innovative plasma-electrochemical technology that can efficiently produce ammonia using only air and water at room temperature. Led by Professor Chris Li, the technology combines the benefits of plasma's nitrogen bond-breaking capability with electrochemical systems' ammonia-selective conditions, marking a significant advancement in the field.
The novel approach addresses the challenges faced by other alternative ammonia-synthesis methods by leveraging the dual nature of plasma and electrochemistry. In this process, air is humidified with water and processed through a plasma field to break nitrogen bonds, forming reactive nitrogen species. These species then react with oxygen and hydrogen to generate a mix of NOxHy compounds, which are subsequently converted into ammonia using an electrochemical reactor.
The research team, led by Li, has achieved stable operation of the reactor system, producing approximately 1 gram of ammonia per day for a duration exceeding 1,000 hours. With aspirations to scale up the technology to levels comparable to fuel cells and electrolyzers, the focus now lies on enhancing energy efficiency and demonstrating feasibility for larger-scale applications.
The study, detailed in the December 2024 edition of the Journal of the American Chemical Society, underscores the significance of computational graph theory in identifying optimal reaction pathways and catalysts for maximizing efficiency. The innovative plasma-electrochemical technology not only offers promise in revolutionizing ammonia production but also highlights the potential for sustainable and energy-efficient practices in chemical engineering.
