“…There are reports of MCM-41 morphologies that include spherical, rodlike, discoids and gyroids, in addition to millimeter-to-micrometer sized particles and hollow spheres, hollow tubes, wormlike, monolithic gels, thin films, among others. Images similar to those reported here in can also be seen elsewhere [41][42][43] Table 4. The experimental design revealed that trial 4 depicted the best result, with CO 2 adsorption of 0.62g/g at 40 bar.…”

There is a growing concern on the relationship between anthropogenic carbon dioxide and climate changes. A promising approach is the adsorption technology using mesoporous MCM-41 materials that can be easily synthesized to depict structures adequate to the flow of gas. The aim of this study was to improve the synthesis of MCM-41 using cationic surfactant mixtures and apply the resulting materials to CO 2 adsorption. To that end, the simplex-centroid design was applied to optimize CO 2 adsorption from seven mesoporous MCM-41 materials synthesized by the hydrothermal method using surfactants from hydrophobic chains of different sizes. The cationic surfactants used were tetradecyltrimetylammonium bromide, cetyltrimethylammonium bromide, trimethyloctadecylammonium bromide and their mixture at ratios of 1:1 and 1:1:1. The CO 2 adsorption was investigated using thegravimetric method at 298 K and pressures up to 40 bar. The resulting materials, labelled C 17 , C 19 , C 21 , C 17 C 19 , C 19 C 21 , C 17 C 21 and C 17 C 19 C 21 , were characterized by XRD, FTIR, TG and SEM and showed significant differences in structure as well as in the mass of CO 2 adsorption. The response models showed that the best combination of the surfactants resulted from C 17 C 19 sample, which presented synergistic interactions reaching the highest value of CO 2 adsorption (0.62 g CO 2 /g adsorbent), compared to other samples.

“…For film preparation on substrates, several synthetic options have been reported [10][11][12][13] besides the solvent evaporation method. To control the macroscopic shape of the sol-gel derived products, reactions under acidic conditions are favorable, partly due to their low and controllable rate compared with those under basic conditions.…”

“…On the other hand, there are few examples of the preparation of silica-surfactant hybrid films without using acidic conditions. The formation of silica-surfactant nanostructures on substrate by the adsorption of a component or silica-surfactant from vapor phase has been reported so far [11][12][13]. To the best of our knowledge, there are few reports on the preparation of mesoporous silica films using basic conditions [12,[14][15][16].…”

“…For the synthesis of mesoporous ordered metal oxides, the combination of self-assembly procedure and inorganic chemistry is essential. Mainly chemical methods such as spray coating, meniscus coating, spin-coating, dip-coating, pulsed laser deposition [5] and electrochemical deposition [6] are used for the preparation of mesoporous metal oxides [7].…”
