“…Then, H 2 PtCl 6 (the Pt precursor) was deposited on the hydrophobic SBA-15 support and reduced to obtain the superhydrophobic catalyst. 57 Since LPCE (liquid-phase catalytic exchange) reaction is a countercurrent reaction, the dynamic contact between catalyst and liquid water has a great impact on the catalytic performance. This hydrophobic catalyst avoids the contact between liquid water and catalyst, and liquid water does not adhere to the catalyst surface.…”

“…Another way to enhance the LPCE performance is by increasing the hydrophobicity of the catalyst. Previous studies reported that Pt/C/PFTE and Pt/SDB catalysts commonly used for the LPCE process have a water contact angle of around 110° [49,[59][60][61]. However, by modifying the catalyst support, the hydrophobicity of the catalyst can be enhanced.…”

Liquid phase catalytic exchange (LPCE) appears a highly promising technology for separating hydrogen isotopes due to being less energy-intensive and having a high separation factor. This paper provides an overview of the current development of the hydrophobic catalysts used in the LPCE process, including the LPCE fundamentals, factors influencing its effectiveness, and proposals for future research areas. This paper specifically reviews the active metal catalysts, catalyst supports, operating temperatures, and molar feed ratio(gas-to-liquid,G/L). The addition of a second metal such as Ir, Fe, Ru, Ni, or Cr and modified catalyst supports showed enhancement of LPCE performance. Additionally, the validated optimized temperature of 60–80 °C and G/L of 1.5–2.5 provide an important basis for designing LPCE systems to improve separation efficiency. This paper concludes by highlighting potential research areas and challenges for future advancements in the sustainability of LPCE for hydrogen isotope separation, which include the optimization, scalability, techno-economic analysis, and life-cycle analysis of modified catalyst materials.

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.
