Catalyst containing metal cluster in structurally collapsed zeolite, and use thereof

A method of preparing a hydrogen spillover-based catalyst, comprising:

• (a) providing zeolite containing a hydrogen activation metal (M) cluster therein and having a silica/alumina molar ratio of 2 or less, wherein the zeolite is P-type zeolite, A-type zeolite or X-type zeolite, wherein the hydrogen activation metal (M) cluster is incorporated into the zeolite using impregnation or ion-exchange;
• (b) ion-exchanging the metal cluster-incorporating zeolite with an ammonium ion (NH4+);
• and
• (c) thermally treating the ion-exchanged zeolite to thus partially or fully collapse a zeolite framework so that the hydrogen activation metal cluster is encapsulated in crystalline or amorphous aluminosilicate,
• wherein changes in hydrogen and carbon monoxide chesnisorption amounts depending on a temperature satisfy the following relation:
• 0.7*(H/M373 +H/M473 +H/M573)/3>(CO/M373 +CO/M473 +CO/M573)/3
• wherein H/M is a chemisorption amount (mol) of a hydrogen atom per total mol of M, CO/M is a chemisorption amount (mol) of carbon monoxide per total mol of M, and subscripts represent adsorption temperatures (K).
