The world is looking for clean and green energy as substitution for fossil fuels to minimize the greenhouse effect and climate changes threatening our existence. Solar energy, wind energy, and hydrogen gas‐based energy are few examples of promising sources of energy alternatives to fossil fuels. Hydrogen gas‐based energy is in focus today due to its availability in plenty of combined forms such as water, hydrocarbons, natural gases, etc. However, its storage and transportation are major challenges due to the low volumetric density and explosive nature of hydrogen. The scientific community is in search of suitable, economically viable, and energy‐efficient storage systems and transportation of hydrogen gas. Based on numerous studies, surface adsorption of hydrogen by high surface area nanoporous solids such as carbon and metal–organic framework (MOF)‐based nanofiber materials are most suitable for storage applications. Electrospinning process provides a gateway for the preparation of lightweight, highly porous nanofibers for efficient hydrogen adsorption. Herein, the production and use of electrospun polymer nanofibers and MOFs for the storage and transportation of hydrogen are presented.

Liquid‐phase catalytic exchange (LPCE) of hydrogen isotopes has extensive application in upgrading of recycled water and wastewater treatment. This low‐temperature catalytic exchange requires hydrophobic catalysts for keeping high exchange efficiency and catalytic stability. To eliminate diffusional influences in conventional porous catalysts, we designed a flat catalyst coating with fully exposed platinum (Pt) active sites by two steps. The hydrophobic coating was firstly established by superhydrophobic silica nanospheres (SSNs) and then Pt nanoparticles were dispersed on the surface of coating by ion sputtering. By adjusting the time of ion sputtering, the catalytic exchange efficiency of optimized catalyst coating (50‐Pt/SSNs/PDMS) improved up to 86% at 60 °C and maintained stability for at least 5 h, behaving high catalytic exchange efficiency and good stability. Besides, the turnover frequency of the 50‐Pt/SSNs/PDMS was 1.7 times than that of “PDMS+Pt/SSNs” prepared by “glue+power” method. The “step by step” strategy can effectively improve the utilization of Pt and provide a new idea for the preparation of Pt‐based hydrophobic catalysts.

“…Because D and T are not directly obtainable as pure isotopes, methods to separate them from the more common, lighter isotope, protium, are required. Many researchers have studied various isotope-separation methods, including water distillation [ 3 ], molecular sieving [ 4 ], water electrolysis [ 5 , 6 , 7 , 8 ] and combined electrolysis catalytic exchange [ 9 , 10 ]. The water electrolysis yields the most effective separation but consumes enormous amounts of electricity.…”

Novel PEFC Application for Deuterium Isotope Separation

et al. 2017

The use of a polymer electrolyte fuel cell (PEFC) with a Nafion membrane for isotopic separation of deuterium (D) was investigated. Mass analysis at the cathode side indicated that D diffused through the membrane and participated in an isotope exchange reaction. The exchange of D with protium (H) in H2O was facilitated by a Pt catalyst. The anodic data showed that the separation efficiency was dependent on the D concentration in the source gas, whereby the water produced during the operation of the PEFC was more enriched in D as the D concentration of the source gas was increased.
