Abstract
The purpose of the present invention is to provide a beta zeolite which includes zinc and has a small particle size. This beta zeolite includes a silicon oxide and a zinc oxide, and has an average particle size of 50 to 100 nm at a cumulative frequency of 50% in a particle size distribution measured by scanning electron microscope observation.
