Researchers at MIT developed a method for predicting the optimal catalyst materials for electrochemical ammonia production, aiming to enhance the cost competitiveness of this low-emission production method. Traditional Haber-Bosch processes rely on fossil fuels, accounting for approximately 2% of global energy consumption and 1.5% of greenhouse gas emissions. While existing electrochemical methods are theoretically feasible, their efficiency and cost remain insufficient for industrial application. The new research was conducted by Billi Yurdiz, a professor of nuclear science and engineering, and materials science and engineering, along with his doctoral students. The study was published in the journal EES Catalysis of the Royal Society of Chemistry. By identifying key physical properties that drive catalytic activity, this method replaces the traditional trial-and-error approach, significantly accelerating the process of screening millions of alloy combinations. Although approximately 200 million tons of ammonia are required worldwide each year to ensure food security, over 90% of it is still produced using high-energy-consuming traditional processes. In the future, there is an urgent need to develop alternative methods with higher energy efficiency and lower carbon emissions.
