CO2 sorption onto silica mesoporous materials made from nonionic surfactants

Performance of metal-functionalized rice husk cellulose for CO2 sorption and CO2/N2 separation

“…Research into CO 2 sorption and separation is currently being carried out in a wide variety of areas. Zeolites [5,6], amine technology [7][8][9], silica [10], silica gel [11,12], mesoporous materials [13,14], poly (ionic liquid)s [15], metal organic frameworks [16][17][18], chemical looping [19], lithium-based ceramics [20] and cellulose [21,22] all provide a potential solution to the ever-growing CO 2 problem. One area of particular interest is the modification of cellulose to enhance its adsorptive properties.…”

Fabrication and characterization of mesoporous silica nanochannels inside the channels of anodic alumina membrane

“…Hence, the localized internal atmosphere inside the nanochannels could control the diffusion and mass transport mechanisms and thus, can be used for selective separation sciences, sensing and catalysis. Moreover, understanding and prediction of the mechanism of interaction which is responsible for the diffusion, extraction and mass transport within the nanochannels (Yamaguchi et al, 2006 and could help achieving many successful applications of confined mesoporous silica membranes such as; diffusion of biomolecules (Gargiulo et al, 2013), adsorption of organic pollutants (El-Safty et al, 2012), biosensors (Itoh et al, 2014;Hotta et al, 2012;Fan et al, 2014), gas sorption (Chalal et al, 2015) and anion detection at the liquid/liquid interface (Gao et al, 2015).…”

An investigation of the textural properties of mesostructured silica-based adsorbents for predicting CO2 adsorption capacity

“…A great variety of materials, such as mesostructured and amorphous silica, alumina, zeolites, metal-organic frameworks, polymers or carbonaceous sorbents have been considered. [1][2][3][4][5] When non-functionalized materials like the ones cited above are used the adsorption mechanism is restricted to physisorption, although some selectivity towards CO 2 has been found in mixtures with N 2 , O 2 , H 2 , CH 4 or Ar. [6][7][8] This fact is explained by the CO 2 adsorption mechanism, which is caused by two different kinds of forces.…”
