Session: General Catalysis:

The development of effective routes to clean energy production and air pollutant elimination is important for energy and environmental sustainability. Catalysis plays a central role in establishing such routes, but a major challenge is the design and preparation of active, robust and low-cost catalysts for the targeted catalytic reactions. Herein, this work reports a highly-effective thermochemical pathway for design, synthesis, and characterization of nanoalloy catalysts for propane oxidation. This study aims at establishing the correlation among the nanoscale phase structures, the nanoparticle composition, the chemical nature of support, and the surface catalytic sites of the catalysts during the catalytic reactions for propane oxidation. In particular, we focus on detecting and monitoring the nanoscale evolution of surface catalytic sites by probing the chemical and intermediate species on the catalysts in correlation with the trimetallic composition and the alloying phase structure. Advanced and analytical techniques such as synchrotron high-energy X-ray diffraction coupled to atomic pair distribution function analysis and diffuse reflectance infrared Fourier transform spectroscopy are employed for in-situ characterizations of the nanocatalysts
