▎ 摘　　要

AgAuPd nanoparticles with small particle size, good dispersity and high degree of crystallinity on graphene are synthesized by a facile co-reduction route. The resultant AgAuPd/graphene exhibits 100% H-2 selectivity, 100% conversion and excellent catalytic activity toward the hydrogen generation from decomposition of formic acid without any additive at room temperature.
