Abstract
Au-doped lithium hydride (LiH) demonstrates significant potential for applications in advanced energy storage systems and radiation absorption. However, due to the large density difference between gold (Au) and LiH, achieving uniform dispersion of Au remains a significant challenge, which hinders the development of Au-doped LiH. Herein, we report a method for achieving uniform Au dispersion. Using LiH as the raw material and parylene as the pore-forming agent, together with Au doping, we successfully synthesized Au-doped foamed LiH. This material has a highly porous structure with uniformly distributed Au particles, with a predominant particle size of 1.7 μm. Discrete element simulation also confirms that small Au particles around LiH achieve the highest uniformity. This material enables a novel synthetic route to metal-doped LiH and offers considerable promise as a dual-functional material for hydrogen storage and radiation shielding.
