Membrane separation, from its infancy as a predominantly laboratory technique in the middle of the last century, has advanced with remarkable speed and now underpins a range of mature industrial technologies. Porous membranes play a crucial role in many commercial applications: the desalination of seawater and brackish water via reverse osmosis and nanofiltration; the clean-up of industrial eff...

A palladium membrane was prepared using the electroless plating technique (ELP) for the separation and purification of hydrogen from a gas mixture. Depending on operating conditions, hydrogen flux from the membrane was in the range of 0.012-0.023 mol.m-2.s-1. The membrane performance in the presence of CO2 was investigated. The results of the GC analysis showed that at a feed concentration of 1...

We 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). The porous silicene exhibits high selectivity comparable with graphene-based membranes for hydrogen over various gas molecule...
