A method for preparing an MCM-41-type catalyst includes: mixing tetraethoxysilane, cetyltrimethylammonium bromide, a metal compound, sulfonated tripropylene glycol methyl ether, sodium hydroxide and water to obtain a mixture solution, the metal compound ranging from 0.03 mole to 0.10 mole based on 1.0 mole of the tetraethoxysilane, the sulfonated tripropylene glycol methyl ether ranging from 0.1 mole to 0.3 mole based on 1.0 mole of the cetyltrimethylammonium bromide; adjusting pH value of the mixture solution to obtain a colloidal solution; subjecting the colloidal solution to a heating treatment, so as to form a catalyst precursor; subjecting the catalyst precursor to a washing process, so as to obtain a washed catalyst precursor; subjecting the washed catalyst precursor to a drying treatment so as to obtain a dried catalyst precursor; and subjecting the dried catalyst precursor to a calcination treatment.
