Effect of Catalyst Preparation Method on Ammonia Decomposition Reaction over Ru/MgO Catalyst

Abstract Ammonia decomposition on Ru/MgO was strongly affected by the pore structure of the MgO support. We found that highly active Ru/MgO catalysts were successfully prepared by using Ru hydroxide and hydromagnesite as catalyst precursors. The mesopores of MgO of about 3–5 nm and highly dispersed Ru species improved the catalytic performance.
