Abstract The mesoporous MCM-41 catalyst was grafted by sulphuric acid via equal volume impregnation method to prepare the H2SO4/MCM-41 catalysts. The structures and properties were characterized by pyridineIR, XRD, N2 adsorption-desorption and NH3-TPD. The results indicated that the best yield of acrolein was 85.5% over H2SO4/MCM-41 catalyst with 10%H2SO4. The mesoporous structures of the catalysts were maintained after modifying, and the acidity and the ratio of Brnsted acid were improved.
