Adsorption separation of heavier isotope gases in subnanometer carbon pores.

ABSTRACT: Isotopes of heavier gases including carbon (¹³C/¹⁴C), nitrogen (¹³N), and oxygen (¹⁸O) are highly important because they can be substituted for naturally occurring atoms without significantly perturbing the biochemical properties of the radiolabelled parent molecules. These labelled molecules are employed in clinical radiopharmaceuticals, in studies of brain disease and as imaging probes for advanced medical imaging techniques such as positron-emission tomography (PET). Established distillation-based isotope gas separation methods have a separation factor (S) below 1.05 and incur very high operating costs due to high energy consumption and long processing times, highlighting the need for new separation technologies. Here, we show a rapid and high
