Summary: Carbon-based membranes were synthesized on porous alumina via a hydrothermal method from aqueous glucose solutions. The hydrothermal treatment time and temperature were evaluated to study their effects on the microstructure of the membranes. The obtained carbon membranes were found to be deposited both on the surface and in the interiors of the porous alumina. The carbon membrane prepared at a hydrothermal treatment of 200 degrees C for 5 hours showed few pinholes and consisted of amorphous carbon with hydroxy groups. Gas transmission rate measurements indicated that the membrane had a pore size of approximately 0.3 nm and exhibited high selectivity for various gas mixtures.

Summary: Researchers have developed a 50 nm thick benzimidazole-linked polymer (BILP) membrane with H2-selective channels based on the controllable formation of benzimidazole rings and precise manipulation of spacing among polymer chains. The highly-selective BILP membranes exhibit H2/CO2 selectivity of up to 56.3 (with a corresponding H2 permeance of 127 GPU). Highly-permeable BILP membranes deliver H2 permeance up to 439 GPU (with a corresponding selectivity of 28.5), surpassing the upper bounds of traditional polymer membranes. The membranes also demonstrate outstanding thermal (e.g. 300 degrees C) and pressure resistance.
