Summary:

The poster presents an innovative solid state chemistry technology for scalable, low-cost, facile, and surfactant-free preparation of cubic and octahedral nanoparticles of platinum group metals (PGMs = Pt, Pd, Rh, Ru, and Ir) and their alloys on different support materials. The nanoparticles of PGMs with tailored morphology are prepared by a dry gas-phase synthesis, which involves impregnation of the metal precursors on support and reduction of the precursors under functional gas atmosphere. The scalable production of shaped PGM nanoparticles, which can exhibit extraordinary property and ensure a more efficient usage of the materials, will no doubt have broad impact on various technologies which rely on the use of these advanced materials, such as fuel cells, chemicals conversion, batteries, and sensors. These technologies can be used in a variety of industries including materials production, transportation, energy generation, communication, and environment control.
