Claims16
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.
A production method for obtaining an aggregate containing alloy nanoparticles, wherein the alloy nanoparticles comprise five or more elements of the platinum group, comprising adding an aqueous solution comprising salts of five or more elements of the platinum group to a liquid reducing agent heated up to 200° C. to 300° C. and reacting them, and causing the alloy nanoparticles to be 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.
