Synthesis of PtZn and PtZn intermetallic nanocatalysts for dehydrogenation of ethane.

PtZn and PtZn intermetallic nanoparticles supported on SiO were synthesized by combining atomic layer deposition (ALD) of ZnO, incipient wetness impregnation (IWI) of Pt, and appropriate hydrogen reduction. The formation of PtZn and PtZn intermetallic nanoparticles was observed by both X-ray diffraction (XRD) and synchrotron X-ray absorption spectroscopy (XAS). STEM images showed that the 2-3 nm Pt-based intermetallic nanoparticles were uniformly dispersed on a SiO support.
