Mesoporous silica nanoparticles (MSNs) were synthesized by sol-gel reaction at normal pressure by using TEOS as a silica source\r\nand CTAB as a directing agent in ammonia solution at 323K subsequently calcined at 823K. Then inorganic pores were modified\r\nwith metal-supported MSN with attention to the acidity, surface area, pore size, and ability of ion exchange. Crystalline size was\r\nshown to decrease up to 20 molar ratios of Si/Al followed by increasing while further adding nanoparticles-aluminium.Moreover,\r\nthe XRD patterns revealed the mesostructured material for all with 2D hexagonal structure. The obtained results from the XRD\r\npatterns were confirmed by using BET and EDX.The BET surface areas revealed the spherical shape for all samples with a decrease\r\nin the pore volume and surface area for various AlMSNs which emphasized that the loading of Al and was compatible with XRD\r\nresults. MSN was prepared by sol-gel methods followed by loading of Al in order to prepare AlMSN which possess strong Lewis\r\nacidic sites. This modification occurred by using various molar ratios of 0, 5, 10, 20, 50, and 100 Si/Al, respectively.The XRD patterns\r\nof various ratios of Si/Al were interpreted in terms of strain, nanocrystalline size, and distribution of the particle size by deriving\r\nWiliamson Hall equation.
