▎ 摘　　要

NOVELTY - A catalyst comprises a dendrimer, and nanoparticles which are made of an alloy of platinum and palladium and reduce activation energy of the hydrogen production reaction, encapsulated inside the dendrimer. USE - Catalyst is used as catalyst complex for hydrolysis dehydrogenation of ammonia borane for producing hydrogen (all claimed) used as fuel in hydrogen vehicles. ADVANTAGE - The catalyst has improved catalytic activity by changing only the nanoparticle composition and by supporting the catalyst on the carrier. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a hydrogen production reaction catalyst complex, which comprises a carbon-based carrier and the catalyst supported on the carbon-based carrier.
