Title:
TRANSITION METAL-CARRYING ZEOLITE AND PRODUCTION METHOD THEREFOR, AND NITROGEN OXIDE PURIFICATION CATALYST AND METHOD FOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/168787
Kind Code:
A1
Abstract:
This transition metal-carrying zeolite is configured such that an absorption intensity ratio in a specific region of the transition metal-carrying zeolite observed by ultraviolet visible light near infrared spectroscopy (UV-Vis-NIR) and an intensity ratio of a maximum peak in a different temperature range of the transition metal-carrying zeolite measured by ammonia temperature-programmed desorption, respectively fall within specific ranges.
