Advances in light isotopes separation and catalytic labeling
Stable light isotopes such as hydrogen,carbon,nitrogen and oxygen are widely used in medical drugs,clinical diagnosis,environmental geology and other fields.The enrichment of high-purity isotopes as raw materials to obtain targeted isotope-labeled compounds are core technology for isotope application.Adsorption separation based on quantum effect displays low energy footprint and high efficiency and thus is considered as a promising method for the purification of isotope gases.Catalytic isotope exchange and functional group conversion reactions are important technologies for isotope labeling.The key for both processes is the development of efficient adsorbents and catalysts.This paper summarizes the recent research progress for isotopes separation and catalytic labeling.Then,the development status of key materials is analyzed along with the strategy for performance optimization.Finally,the research challenges and developing trends in this field are prospected.
