Lithium Fluoride Enhanced Platinum Catalytic Exchange of Hydrogen Isotopes by High Hydrogen Adsorption at Low Temperature
The catalytic exchange of hydrogen isotopes is a promising technology for purifying recycled water in nuclear power stations. However, it remains a challenge for achieving high catalytic efficiency and stability at low temperatures. In this work, we propose a facile strategy to enhance the catalyst efficiency by introducing LiF in the Pt/Ti3AlC2 (Pt−5-LiF/Ti3AlC2). The incorporation of LiF significantly achieves high catalytic exchange efficiency of 92 % and a turnover frequency of 28.1 h−1, which are more than twice that of Pt/Ti3AlC2. The structure-activity relationship analysis reveals that the introduction of LiF substantially enhanced the hydrogen adsorption capacity of the catalyst and further improved the performance of the catalysts. Moreover, this LiF-added strategy is also applicable to other Pt-based catalysts such as Pt/Al2O3 and Pt/activated carbon. This work provides a novel catalyst design strategy for high-efficiency catalytic exchange of hydrogen isotopes.
