Ammonia decomposition catalyst and method of decomposing ammonia using the catalyst
Provided are an ammonia decomposition catalyst and a method of decomposing ammonia. The ammonia decomposition catalyst includes an activated carbon carrier and a metal loaded on the carrier, wherein a Brunauer, Emmett and Teller (BET) specific surface area of the carrier is about 850 m 2 /g or more, and the metal includes cerium (Ce).
1. An ammonia decomposition catalyst comprising:
an activated carbon carrier; and
a metal loaded on the carrier,
wherein a Brunauer, Emmett and Teller (BET) specific surface area of the carrier is 850 m 2 /g or more, and the metal consists of cerium (Ce) and zirconium (Zr),
wherein an amount of Ce is greater than an amount of Zr.
2. The ammonia decomposition catalyst of claim 1 , wherein an amount of the metal is in a range of about 0.15 parts to about 10 parts by weight based on 100 parts by weight of the carrier.
3. A method of decomposing ammonia in an ammonia-containing gas according to Reaction Scheme 1,
wherein the method of decomposing ammonia in an ammonia-containing gas is performed under conditions of relative humidity of about 70% or higher and room temperature of about 30° C. or lower in the presence of ozone and the ammonia decomposition catalyst according to claim 1 :
[Reaction Scheme 1]
2NH 3 +O 3 →N 2 +3H 2 O.
