nanostructured mesoporous composites by interconnecting and combining SBA-15 with mixed oxides derived from a calcinedMg–Alhydrotalcite. Two different Mg–Al hydrotalcite addition procedures were implemented, either after or during the SBA-15 synthesis (in situ method). The first procedure, i.e., the post
might be utilized as as acid-base catalysts, adsorbents, sensors or storage nanomaterials.
Keywords: calcinedMg–Alhydrotalcite; nanoporous composites; SBA-15; vapor sorption; Introduction
Multifunctional nanomaterials are designed to satisfy specific ranged sets of performance requirements. The
prepared composites and the SBA-15 show H1 hysteresis loops due to the N2 capillary condensation. It also denotes that the pores present a cylindrical form and narrow size distribution (Figure 1B).
