Room-temperature in situ synthesis of MOF@MXene membrane for efficient hydrogen purification
Journal of Membrane Science, 2022MXene-based membranes with well-defined nanochannels are promising for gas separation. However, manipulating the interlayer structure to obtain high permeance and selectivity remains a great challenge.

Nanofilter for hydrogen purification
International Journal of Hydrogen Energy, 2003Abstract The application of polymeric membranes in combination with metallic films can be used for gas purification, in particular hydrogen (Int J Hydrogen Energy 27(2) (2002) 905), whose molecules are very small. The affinity of hydrogen to certain metals supports its flow, but restricts the permeation of other gases.

Purification of hydrogen from natural gas/hydrogen pipeline mixtures
Separation and Purification Technology, 2022Abstract There is an increasing global attention toward hydrogen as a green energy carrier, primarily because of the environmental concerns associated with global warming issues. It is expected that the produced hydrogen from various sources may be injected to the natural gas grid for economical transportation and use.

Graphdiyne as Hydrogen Purification Membrane
Chinese Journal of Chemical Physics, 2012The permselectivity of H2/O2, H2/N2, H2/CO, and H2/CH4 mixtures passing a graphdiyne membrane is studied by molecular dynamics simulations. At pressure range of 0.047–4.5 GPa, H2 can pass the graphdiyen membrane quickly, while all the O2, N2, CO, and CH4 molecules are blocked. At pressure of 47 kPa, the hydrogen flow is 7 mol/m2s.

Porous silicene as a hydrogen purification membrane
Physical Chemistry Chemical Physics, 2013We investigated theoretically the hydrogen permeability and selectivity of a porous silicene membrane via first-principles calculations. The subnanometer pores of the silicene membrane are designed as divacancy defects with octagonal and pentagonal rings (585-divacancy).
