1. An aggregate containing alloy nanoparticles, wherein the alloy nanoparticles comprise five or more elements of the platinum group and
wherein the alloy nanoparticles are directly supported on a granular carrier selected from the group consisting of oxides, nitrides, carbides, and a granular carbon carrier, with the proviso that the granular carbon carrier is not graphene or carbon fibers.
