▎ 摘　　要

NOVELTY - Low-temperature high-efficiency ammonia decomposition catalyst, comprises Santa Barbara amorphous-15-graphene (SBA-15-G) as carrier, and nickel as active ingredient. USE - The low-temperature high-efficiency ammonia decomposition catalyst is useful in ammonia decomposition hydrogen production reaction (claimed). ADVANTAGE - The catalyst: has higher ammonia decomposition activity at low temperature compared with the existing nickel-based catalysts; and exhibits high catalytic activity and stability in the ammonia decomposition reaction. The method: is simple; and has low cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing low-temperature high-efficiency ammonia decomposition catalyst, comprising (i) preparing composite carrier Santa Barbara amorphous-15-graphene by sol-gel method, and (ii) mechanically mixing nickel precursor salt and the composite carrier Santa Barbara amorphous-15-graphene in an aqueous solution, and drying the composite carrier Santa Barbara amorphous-15-graphene and calcining under ammonia atmosphere to obtain final product.
