Hydrogen has long been considered an attractive fuel source due to its potential for zero greenhouse gas emissions and sustainability. However, the challenges of hydrogen storage and release have hindered its commercial use in vehicles. Recent research has focused on ammonia borane (AB) as a high-capacity hydrogen storage material, with catalysts facilitating the release of hydrogen from AB solution. Amorphous domains in metallic Fe Foam have been synthesized to enhance catalytic activity for AB hydrolysis, achieving notable performances and increasing catalyst stability. The Fe Foam, after oxidation and reduction, showed efficient production of hydrogen from AB, meeting the U.S. Department of Energy targets for hydrogen storage capacity. The innovative approach of combining bulk Fe crystal structure with amorphous domains holds promise for enabling the use of AB chemical storage in hydrogen-powered vehicles. The study demonstrated that R-Fe2O3 Foam can produce 201mL of hydrogen from 1mol AB in 7.5 minutes, showcasing high catalytic activity and stability. This research signifies a significant step towards efficient and stable hydrogen production for sustainable energy applications.
