Nanoflower, nanoplatelet and nanocapsule Mg(OH)2 powders for adsorption of CO2 gas

Cu(II) and Gd(III) doped boehmite nanostructures: a comparative study of electrical property and thermal stability

“…The type-IV isotherm (figure 6) obtained from the data indicates that the undoped (NBH) sample is mesoporous, having a pore diameter of 3.53 nm in our samples [47,48]. H4-type hysteresis loops were obtained for all the samples, indicating the formation of slit-like pores [47,48]. From the BET data, it is quite evident that the surface areas of the doped boehmite samples enhanced quite significantly.…”

“…Surface areas of the synthesized nanostructures corresponding to the nitrogen (N 2 ) adsorption-desorption isotherms and their corresponding pore size distributions are illustrated in figure 5. The type-IV isotherm (figure 6) obtained from the data indicates that the undoped (NBH) sample is mesoporous, having a pore diameter of 3.53 nm in our samples [47,48]. H4-type hysteresis loops were obtained for all the samples, indicating the formation of slit-like pores [47,48].…”

Inorganic Nanomaterials for Restoration of Cultural Heritage: Synthesis Approaches towards Nanoconsolidants for Stone and Wall Paintings

“…Each counterion from the different magnesium salts acts as a surface modifier, so that the nucleation and growth of crystal seeds are consistently and systematically influenced. For instance, precipitation of the nitrate, chloride, and bromide salts of magnesium with NaOH at 30 °C leads to the formation of nanoflowers composed of self‐assembled nanoplatelets derived from the chloride and nitrate starting salts and to the formation of nanocapsules derived from the bromide starting salt …”

Hypercrosslinked silole‐containing microporous organic polymers with N‐functionalized pore surfaces for gas storage and separation

“…[3][4][5] Nevertheless, this process shows several inherent shortcomings including erosion of equipment and high regeneration costs. 6,7 A cheap alternative solution to this problem is physical sorption of CO 2 by microporous organic polymers (MOPs), as their readily reversible adsorption-desorption behavior allows materials regeneration without applying heat. 8 To date, a range of MOPs such as covalent organic frameworks, 9,10 polymers of intrinsic microporosity, 11 hypercrosslinked polymers (HCPs), 12 conjugated microporous polymers, [13][14][15] covalent triazine-based frameworks, 16 and porous polymer networks 17 constructed from lightweight elements through strong covalent bonding have become a focus of attention.…”

“…Current methods such as amine scrubbing and CaO‐based sorption have been commonly employed to capture CO 2 from the flue gases through a reversible chemical reaction . Nevertheless, this process shows several inherent shortcomings including erosion of equipment and high regeneration costs . A cheap alternative solution to this problem is physical sorption of CO 2 by microporous organic polymers (MOPs), as their readily reversible adsorption–desorption behavior allows materials regeneration without applying heat .…”
