Abstract
ZSM-5 Mesoporous with variation ratios of SiO2/Al2O3 20, 35, 50, and 100 have been
successfully synthesized. Phase of mesoporous created using Cetyltrimethylammonium bromide (CTABr)
templates. Crystal obtained has an acidity and higher thermal stability. Diffraction peaks typical of ZSM-5
appeared at 2θ = 7-9 and 2 θ = 23.02 , while typical peak of mesoporous materi als appeared on 2θ <5.
Surface acidity is determined using pyridine adsorption with FTIR analysis. The increases ratio of
SiO2/Al2O3 causes the number total acid side of Brønsted decrease while the total acid side of the Lewis
increased.
