“…Although from Table , it is seen that P5 powder has lower pore wall thickness, the rupturing of mesopore structure upon the application of high sonication energy makes it a very low surface area powder. Figure shows the comparison of H 2 adsorption capacity of SBA‐15 powders synthesized in this work with other reported values of hydrogen adsorption by other different materials . It is clear that the present result of hydrogen adsorption capacity of the high surface area powder P4 is higher than the reported value till date.…”

In the present report, mesoporous silica SBA‐15 was synthesized by different methods such as room temperature aging, hydrothermal, and sonication‐mediated hydrothermal methods. The effect of different time and temperature on the synthesis method was investigated by conventional characterization techniques. The powders synthesized by different methods showed different properties, mainly in morphology and pore volume. In comparison to others, the powder synthesized by the hydrothermal method at 100°C for 48 hours showed exceptionally high surface area of 3274 m2/g. To date, as per our knowledge, no such value was reported in literature. Finally, the powders were characterized by H2 storage capacity by the adsorption‐desorption method using 99.999% H2. The hydrogen adsorption capacity of the same powder was observed at 6.02 wt%. Also, this value seems to be the highest H2 adsorption capacity in comparison to other powders described in literature.

“…It is observed that the CTMA + was fully removed from the mesoporous structure due the vibration bands in 2930-2854 cm -1 range, typical of C-H stretching bonds of CH2 and CH3 groups on CTMA + species. It is also observed at 1487 cm -1 the asymmetric deformation of methyl group (CH3-N + ) disappearing after calcinations process [24]. The bands around 1555 and 693 cm -1 are attributed to NH deformation bond, evidencing the process of functionalization of the mesoporous silica [25].…”

Mesoporous silicas have properties that allow their wide chemical application, due to the large amount of silanol groups on their walls. The possibility of introducing functional groups inside and on the surface of their pores becomes viable the use of these functionalized mesoporous materials for the adsorption of metal ions. Cooper ions are essential for vital functions, but in high concentrations, they are responsible for causing problems to the human organism. Therefore, it is important to monitor the species in different media, such as sugar cane spirit. Mesoporous materials type MCM-41 functionalized were obtained by three different methods using direct (in situ) and indirect (post-synthesis) routes. The mesoporous materials have exhibited properties according to the IUPAC classification. Modified carbon paste electrodes (MCPEs) were prepared by immobilizing the synthesized materials for Cu2+ analysis. The modified electrode obtained by the immobilization of functionalized mesoporous R2 (MCPE/R2) presented the best sensitivity for Cu2+ detection. Under optimum experimental conditions, the MCPE/R2 exhibited a linear range in between 0.99 and 11.80 μmol L-1, a sensitivity based on the Limit of Detection (LOD) of 0.50 μmol L-1and Limit of Quantification (LOQ) of 0.99 μmol L-1, precision (DPRmáx) equals to 10.6% and recovery of 92.2%. The developed method proved to be efficient for Cu2+ determination in sugar cane spirit and the accuracy of the results were comparable to those obtained by AAS.

“…The main properties of nanoporous materials, which can be modified in order to improve hydrogen adsorption, are the adsorbent-adsorbate interaction, specific surface area, geometry and pore size. In addition, the incorporation of metals in nanoporous materials has shown to improve H 2 adsorption, both at 77 K and room temperature [5,6]. This behavior could be related with the affinity of metals towards H 2, suggesting that highly dispersed metal clusters or nanoparticles on nanoporous supports can enhance hydrogen uptakes [7].…”
