Surface Oxidation and Dissolution of Metal Nanocatalysts in Acid Medium
… is concluded that the dissolution mechanism of metal atoms involves: 1) Surface segregation of alloy atoms, 2) oxygen absorption into the subsurface of the catalyst, and 3) metal detachment through the interaction with ions in the solvent. Therefore, to improve the durability of platinum-based …

Catalytic Studies Of Noble Metal Nanocatalysts Using Single-Molecule Fluorescence Microscopy
Noble metal nanoparticles are an important class of catalysts. However they are inherently heterogeneous, which makes studying them at the single-particle level desirable, as it then becomes possible to quantify these differences. A highthroughput fluorescence microscopy technique was developed in …

Non-noble metal nanocatalysts for the purification and reduction of carbon dioxide
… at hand. Nanostructures based on non-noble metals have been traditionally understudied due to their high chemical instability in both synthesis and application. The unique sensitivity and chemical reactivity of their nanostructures, however, offer the possibility for designing new catalytic …

Continuous production of supported and shaped metal nanocatalysts using conveyor transport system
… continuously a family of supported and shaped metal nanocatalysts in a single-step process. With carbon monoxide (CO) as a major species to mediate the surface structures of metals, highly uniform cubic Pt/C with narrow size distribution could be synthesized in a continuous fashion; shaped …

Orbital Level Understanding of Adsorbate-Surface Interactions in Metal Nanocatalysis
… for a priori estimation of catalytic activity of metal nanoparticles using geometry-based reactivity descriptors of surface atoms and kinetic analysis of reaction pathways at various types of active sites. We show that orbitalwise coordination numbers 𝐶𝑁<sup>α</sup> (α = 𝑠 or 𝑑) can be used to …
