Abstract
A nitrogen-based complex hydride is investigated for hydrogen isotope separation for the first time. The experimental results show that a lithium amide-lithium hydride composite (Li-N-H) possesses a distinct positive isotope effect with a separation factor of 1.42. The H-D exchange process in this system occurs at 373 K and can be accelerated with the increase of temperature.
