Isotopic separation is of paramount importance for producing high-purity heavy hydrogen, yet the process remains hugely challenging. Here, we report on an Fe/ZSM-5 zeolite that was able to efficiently separate deuterium from protium via chemical quantum sieving. Structural data showed that four types of Fe species were present in …
