Correlating Structure and Function of Metal Nanoparticles for Catalysis

Abstract

a b s t r a c t 6 a r t i c l e i n f o 7 8Available online xxxx This paper summarizes several studies correlating the structure and function of nanoparticle catalysts. Three 17 types of alloy nanoparticles are considered, random alloy, core@shell and alloy-core@shell structures. In the 18 first two cases, the focus is to build theoretical models to understand previous experimental results. In the latter 19 case, calculations play a greater role in leading the development of nanoparticle catalysts. We demonstrate that 20 iteration between theory and experiment can facilitate an understanding of nanoparticle catalysts and reduce the 21 time and effort involved in the design of new catalysts. 22

Crystal structure of bis[tetrakis(triphenylphosphane-κP)silver(I)] (nitrilotriacetato-κ4N,O,O′,O′′)(triphenylphosphane-κP)argentate(I) with an unknown amount of methanol as solvate

“…Metal nanoparticles are well known in the literature for their use in various applications, e.g., in joining processes (Hausner et al, 2014), catalysis (Steffan et al, 2009;Zhang et al, 2015) and electronics (Gilles et al, 2013;Scheideler et al, 2015). This is caused by the size and shape-dependent properties of the nanoparticles (Wilcoxon & Abrams, 2006).…”

Effects of ensembles, ligand, and strain on adsorbate binding to alloy surfaces

“…Alloys have been widely studied for heterogeneous catalysis, 1,2 sensor design, 3 and energy storage. 4 Many bi-and multi-metallic alloys exhibit enhanced performance as compared to their monometallic counterparts.…”

AuxPd(300‐x) Alloy Nanoparticles for the Oxygen Reduction Reaction in Alkaline Media

“…To be clear, the notation G6OH(Au x Pd (300‐x) ) refers to the ratio of total metal ions (Au+Pd=300) to the number of G6OH dendrimers used for the synthesis. It is not intended to suggest that every NP of a particular average composition has exactly the indicated stoichiometry (though previous studies indicate a close correspondence between the ratio of ions used in the synthesis and the final NPs) . All syntheses were conducted in an ice bath (∼10 °C) under an Ar‐saturated atmosphere.…”
