Title:
ALKANE DEHYDROGENATION CATALYST, AND HYDROGEN PRODUCTION METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2021/015250
Kind Code:
A1
Abstract:
Provided are: a catalyst that is used in a reaction for producing hydrogen from an alkane without emission of CO2; a method for producing hydrogen without emission of CO2 by using the catalyst; and a method for producing ammonia using, as a reducing agent, hydrogen produced using the catalyst. The alkane dehydrogenation catalyst according to the present disclosure contains a graphene having at least one structure selected from an atom vacancy structure, a 1-hydrogenated atom vacancy structure, a 2-hydrogenated atom vacancy structure, a 3-hydrogenated atom vacancy structure, and a nitrogen-substituted atom vacancy structure. The graphene preferably has 2-200 of the structures per 100 nm2 of the atomic film of the graphene. In addition, the hydrogen production method according to the present disclosure includes a step for extracting hydrogen from an alkane by using the alkane dehydrogenation catalyst.
