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.

With the growing demand for fuel and simultaneous pollution caused by the use of traditional fuel sources, the quest for clean energy sources is the biggest challenge forward. This has paved a way for the hydrogen economy. Herein, the successful fabrication of novel cellulose acetate (CA)/palladium acetate (PdOAc)2 blend membranes for hydrogen gas separation with respect to carbon dioxide and methane gases is reported. Pristine CA and CA/(PdOAc)2 blend membranes with various concentrations (0.5, 0.75, and 1 wt %) of (PdOAc)2 were prepared via vapor-induced phase separation (VIPS) method. The membranes were investigated through various techniques such as attenuated total reflectance infrared spectroscopy (ATR-IR) spectroscopy to study the interaction between the CA and (PdOAc)2. Then, a morphological study by field emission scanning electron microscopy (FESEM) showcased homogeneous blending between CA and (PdOAc)2. X-ray diffraction (XRD) patterns revealed the characteristic peaks denoting (PdOAc)2 and change in the crystallinity of the membranes upon blending. The alteration in the mechanical strength of the blends due to the incorporation of (PdOAc)2 into the CA matrix was deliberated by tensile strength analysis. Gas experiments showcased permeability in the descending order of H2 > CO2 > CH4, with a selectivity of 2.02, 68.5, and 34 for H2/CO2, H2/CH4, and CO2/CH4 separation respectively for the optimum membrane. The study was able to demonstrate a simple yet effective way to fabricate membranes with decent separation efficiency for hydrogen gas, giving a boost to the ongoing expedition to use hydrogen gas as a fuel.

“…When it comes to industry, it can also be used as fuel for nuclear fusion, which has the potential to bring energy revolution in the future. − There are many D 2 separation technologies from H 2 , such as heavy water decomposition, cryogenic distillation, electrolysis, and thermal diffusion. However, these technologies usually produce a little energy but consume a lot of energy. − This is exactly why highly efficient H 2 /D 2 separation is a long-time problem. Recently, some new methods for separating hydrogen isotope mixtures have also been developed on a large scale, like chromatography, electrochemical hydrogen pumping, and adsorption separation.…”

Kinetic quantum sieving (KQS) based on pore size and chemical affinity quantum sieving (CAQS) based on adsorption site are two routes of porous materials to separate hydrogen isotope mixtures. Alkali earth metals (Be, Mg, and Ca) were doped into UiO-67 to explore whether these metal sites can promote H 2 /D 2 separation. Based on the zero-point energy and adsorption enthalpy calculated by density functional theory calculations, the Be dopant shows better H 2 /D 2 separation performance than other alkali earth metal dopants and unsaturated metal sites in metal−organic frameworks based on CAQS. Orbital interaction strongly relates to the chemical affinity and further influences the D 2 /H 2 selectivity. Moreover, the predicted D 2 /H 2 selectivity of Be-doped sites (49.4) at 77 K is even larger than the best experimental result (26). Finally, the different dynamic behaviors of H 2 and D 2 on Be-doped UiO-67 indicate its strong H 2 /D 2 separation performance via KQS.
