Beschreibung
Zusammenfassung:	This transition metal-loaded zeolite is configured such that an absorption intensity ratio in a specific region of the transition metal-loaded zeolite observed by ultraviolet-visible-near infrared spectroscopy (UV-Vis-NIR) and an intensity ratio of a maximum peak in a different temperature range of the transition metal-loaded zeolite measured by ammonia temperature-programmed desorption, respectively fall within specific ranges.
