Abstract: A catalyst for an ammonia decomposition reaction and a hydrogen production method using the catalyst are proposed. The shape of cerium oxide used as a catalyst carrier for the catalyst is controlled, and cesium (Cs) is included in the catalyst as a catalyst enhancer. Thus, the catalyst increases an ammonia conversion rate and has improved long-term stability.

Abstract: The present invention relates to an ammonia decomposition catalyst that converts ammonia into hydrogen and nitrogen. The catalyst includes ruthenium (Ru) as an active catalytic component and a composite oxide solid solution (LaxCe1-xOy) including lanthanum oxide and cerium oxide as a catalyst support. The present invention also relates to an ammonia decomposition method using the catalyst and a hydrogen production method using the catalyst.
