Abstract
A novel MFI zeolite that when used as a catalyst, can be used for a selective catalytic reaction for larger molecules and provides a method for producing the MFI zeolite. The MFI zeolite includes uniform mesopores having a pore distribution curve which a peak-width thereof at half height (hw) is at most 20 nm (hw≦20 nm) and a center value (μ) of a maximum peak is 10 nm or more and 20 nm or less (10 nm≦μ≦20 nm), and having a pore volume (pv) of the uniform mesopores of at least 0.05 mL/g (0.05 mL/g≦pv); the MFI zeolite has no peak in a range of 0.1° to 3° in powder X-ray diffraction measurement with a diffraction angle represented by 2θ; and the MFI zeolite has an average particle diameter (PD) of at most 100 nm (PD≦100 nm).
