A study by scientists at Hunan University introduces a new hydrogen isotope separation method that leverages proton quantum tunneling to produce heavy water, overcoming the key physical limitation faced by current methods that have made the production process difficult and expensive for decades.
According to results published in Proceedings of the National Academy of Sciences, this new strategy achieves a record-high H2O separation factor of 276 at room temperature by designing through-barriers that allow hydrogen nuclei to pass through them via quantum tunneling, leaving deuterium behind.
By leveraging quantum mechanics, the method could pave the way for cleaner and more efficient production of a critical material for future energy technologies.
