“…The gaps between the carbon layers in the crystallite structure form ultra-micropore (< 0.6 nm), and the disordered stacking of carbon crystallites forms micropores of larger sizes (0.6-2 nm). The former plays a role in molecular sieve separation, while the latter is for permeation [58]. Compared with the industrialized zeolite membrane, the pores of CMS membranes are slit-shaped, which ensures selectivity and higher gas permeability…”

Porous membrane separation is a competitive hydrogen purification technology due to the advantages of environmental friendliness, energy-saving, simple operation, and low cost. Benefiting from the booming development of materials science and chemical science, great progress has been made in H 2 separation with porous membranes. This review focuses on the latest advances in the design and fabrication of H 2 separation inorganic microporous membranes, with emphasis on the synthetic strategies to achieve structural integrity, continuity and stability. This review starts with a brief introduction to the membrane separation mechanisms, followed by an elaboration on the synthetic challenges and corresponding solutions of various high-performance inorganic microporous membranes based on zeolites, silica, carbon, and metal-organic frameworks (MOFs). At last, by highlighting the prospects of ultrathin two-dimensional (2D) porous membranes, we wish to shed some light on the further development of new materials and membranes for highly efficient hydrogen separation.

Nanoparticles can suppress asymmetric precursor support collapse during pyrolysis to create carbon molecular sieve (CMS) membranes. This advance allows elimination of standard sol–gel support stabilization steps. Here we report a simple but surprisingly important thermal soaking step at 400 °C in the pyrolysis process to obtain high performance CMS membranes. The composite CMS membranes show CO2/CH4 (50:50) mixed gas feed with an attractive CO2/CH4 selectivity of 134.2 and CO2 permeance of 71 GPU at 35 °C. Furthermore, a H2/CH4 selectivity of 663 with H2 permeance of 240 GPU was achieved for promising green energy resource‐H2 separation processes.
