The trade-off between physical adsorption capacity and selectivity of porous materials is a major barrier for efficient gas separation and purification through physisorption. We report control over pore chemistry and size in metal coordination networks with hexafluorosilicate and organic linkers for the purpose of preferential binding and orderly assembly(More)
Hollow or porous hematite (α-Fe2O3) nanoarchitectures have emerged as promising crystals in the advanced materials research. In this contribution, hierarchical mesoporous α-Fe2O3 nanoarchitectures with a pod-like shape were synthesized via a room-temperature coprecipitation of FeCl3 and NaOH solutions, followed by a mild hydrothermal treatment (120°C to(More)
C4 olefin separations present one of the grand challenges in hydrocarbon purifications due to their similar structures, in which case single separation mechanism often met with limited success. Here we report a series of anion-pillared interpenetrated copper coordination networks with fine-tuning cavity and functional site disposition in 0.2 Å scale(More)
With more and more network coding methods being put forward, the metric of network coding performance becomes a key issue in network coding application. In this paper, relative traffic gain (RTG) is proposed to measure the performance of network coding; it is defined as the expected value of the ratio of saved traffic flows to the sum of all traffic flows.(More)
The efficient capture of SO2 is of great significance in gas-purification processes including flue-gas desulfurization and natural-gas purification, but the design of porous materials with high adsorption capacity and selectivity of SO2 remains very challenging. Herein, the selective recognition and dense packing of SO2 clusters through multiple synergistic(More)
Here we report a facile and effective strategy for the preparation of ordered mesoporous carbon materials with a high-nitrogen-content (8.1 at%) coating layer through a polymer-ionic liquid assembly strategy. The prepared N-doped mesoporous carbon materials demonstrated enhanced CO2 adsorption capacity (2.29 mmol g-1) compared with non-doped carbon (1.84(More)
