Organosilane-assisted synthesis of ordered mesoporous poly(furfuryl alcohol) composites

Hydrophobic micro/mesoporous silica spheres assembled from zeolite precursors in acidic media for aromatics adsorption

“…In Fig. 6a, the isotherms for water adsorption on MMS-0 at all the tested temperatures are of type V, indicating the weak interaction between adsorbent and adsorbate [44]. These results are very similar to the behavior of water adsorption isotherm on SBA-15 [45].…”

“…It is interesting to note that there is no capillary condensation for the isotherms of MMS-24. The difference in capillary condensation behavior between MMS-0 and MMS-24 is possibly attributable to their different hydrophobic/hydrophilic properties [44]. In comparison with isotherms on MMS-24 ( Fig.…”

Adsorption performance of VOCs in ordered mesoporous silicas with different pore structures and surface chemistry

“…In Fig. 3a, it is apparent that all of the adsorption isotherms are of type IV (IUPAC classification), with a sharp capillary condensation step at intermediate P/P o , indicating the presence of uniform mesopores [34]. Despite the decrease in the adsorbed amount of nitrogen, the shapes of the hysteresis loops for phenylgrafted samples remain the same as those before functionalization, implying that the functionalization does not change the pore shapes of the silicas [35].…”

Investigation on the Low-Temperature Transformations of Poly(furfuryl alcohol) Deposited on MCM-41

“…MCM-41 with deposited carbon has smaller pores but larger than microporous PFA-based carbon alone and shows higher adsorption of polar volatile organic compound. On the other hand, the proposed synthesis route allows to omit the complicated methods of mesoporous PFA-based carbon synthesis reported earlier [57,58]. In this work, we propose a new, simplified method for the synthesis of poly(furfuryl alcohol)-derived carbon supported on mesoporous MCM-41 silica molecular sieve.…”
