“…Because the qTP1-Mg membrane has a slightly larger pore size, its H 2 permeance is higher than that of the qTP2 membrane, with lower H 2 /CO 2 and H 2 /O 2 selectivities (Figure S3). If we plot the selectivity values against the H 2 permeance and compare the performance with other materials, − one can see that the two qTP membranes surpass the Robeson upper bounds for H 2 /CO 2 and H 2 /O 2 separations by a large margin (Figure ).…”

Hydrogen separation membranes are a critical component in the emerging hydrogen economy, offering an energy-efficient solution for the purification and production of hydrogen gas. Inspired by the recent discovery of monolayer covalent fullerene networks, here we show from concentration-gradient-driven molecular dynamics that quasi-square-latticed monolayer fullerene membranes provide the best pore size match, a unique funnel-shaped pore, and entropic selectivity. The integration of these attributes renders these membranes promising for separating H2 from larger gases such as CO2 and O2. The ultrathin membranes exhibit excellent hydrogen permeance as well as high selectivity for H2/CO2 and H2/O2 separations, surpassing the 2008 Robeson upper bounds by a large margin. The present work points toward a promising direction of using monolayer fullerene networks as membranes for high-permeance, selective hydrogen separation for processes such as water splitting.

“…The development of efficient separation technology is urgently required to capture CO 2 from ue gas and achieve the goal of carbon neutrality. [1][2][3] In addition, CH 4 /N 2 separation is also challenging but needed in the upgrading of unconventional natural gas. 4 Membrane-based separation technology offers signicant merits over other gas separation technologies, including energy efficiency, low cost, and simple process design, and thus shows broad prospects in industrial gas separation.…”

“…Because organic reactions take place at temperatures lower than the BNPs phase change. Therefore, Boehmite nanomaterials have also attracted attention in absorbent, 27 coatings, 28 flame retardant, 29 optical material, 30 ceramics, 31 vaccine adjuvants, 32 cosmetic products, 2,33 pillared clays and sweep-flocculation for fresh water treatment. 13 Consequently, we investigated a new complex of cobalt with 1,3-bis(pyridin-3-ylmethyl)thiourea on boehmite nanoparticle (Co-(PYT) 2 @BNPs) as a reusable nanocatalyst in the synthesis of tetrazole derivatives.…”
