Synthesis of monodisperse platinum nanoparticles supported on carbon gel microspheres

Monodisperse platinum nanoparticles were successfully fabricated on the porous structure of carbon gel microspheres with a narrow pore size distribution. The size of the platinum nanoparticles supported on the carbon gel microspheres was almost coincident with the pore size of the carbon gel microspheres. The results indicated the potential for controlling the size distribution of the supported platinum nanoparticles using the carbon gel microspheres with different pore size distributions.
