摘要：
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.
