Chemical Separation: Finely Tuned Submicroporous Thin‐Film Molecular Sieve Membranes for Highly Efficient Fluid Separations (Adv. Mater. 22/2020)

Novel thin-film composite membranes containing entrapped structural submicroporosity (pore size of <4 Å) exhibit superb performance for removal of small solutes from aqueous or organic solutions, as discussed by Ingo Pinnau and co-workers in article number 2001132. The membranes potentially lower the energy burden and improve the environmental sustainability of chemical separations, which are currently based on thermal principles and account for approximately 10–15% of the world’s total energy consumption.
