Nuzzo, Ralph G. Nuzzo, Ralph G. Gewirth, Andrew A. Murphy, Catherine J. Zuo, Jian-Min Small, Matthew 2013-02-03T19:17:05Z 2013-02-03T19:17:05Z 2015-02-03T11:00:49Z 2012-12 2013-02-03T19:17:05Z 2012-12 Because of their importance to energy production, understanding and improving catalytic materials is essential to further advances in their development and use. The following work discusses the experimental investigation of various supported and unsupported noble metal nanoparticles using, predominantly, X-ray absorption spectroscopy (XAS) and scanning transmission electron microscopy (STEM) or spherical aberration-corrected STEM (Cs-STEM). Although the majority of the work focuses on γ-Al2O3 supported nanoparticles because of their industrial importance for fuel production, several other systems are also addressed. These include understanding the structural characteristics of unsupported noble metal nanoparticles (Au, Ag, Pt, Pd, Ir and Rh) as a function of size and Pt-Pd nanoparticles formed in core-shell, reverse core-shell and alloy motifs. Regardless of the system investigated, all experiments revealed information about how the nanoparticle catalysts were structured and/or behaved under catalytic conditions.
