The chemical surface of Santa Barbara Amorphous-15 (SBA-15) was functionalized with polyaniline (SBA-15/PA) and prepared using aniline ammonium persulfate as the modifying agent oxidant. samples were characterized by N2 physical adsorption at 77 K. SBA-15′s area 654.5 m2 g−1, changing to 254.6 g−1. total acidity basicity determined a modified Boehm’s method, point zero charge pH (pHpzc) determi...

A MOF-5 [Zn(4)O(BDC)(3); BDC = 1,4-benzenedicarboxylate]@SBA-15 hybrid material has been prepared by using SBA-15 as a matrix. This hybrid material exhibits improved hydrostability under ambient conditions and unique gas adsorption behavior compared with pristine MOF-5.

The hyperbolic geometry of the pores in SBA-15 are drawn into a three-dimensional structure by small lateral pores, distributed in a random way, as shown in the picture, which interconnect the main channels. This construction was established by forming a "negative" of the structure with platinum precipitated in the channel and dissolving the SBA-15 material.

The primary goal of this preparation method was synthesis of uniformly coated ZrO2/SBA-15 materials exhibiting high dispersion and accessibility of zirconium using a layerwise deposition method to minimize growth of large crystallites. SBA15 was prepared the original method by Zhao et al.1 First 10g of SBA-15 was dried at 300°C for 4 hours. Then the dried SBA-15 and 58.5g of zirconium precursor...
