Nanoparticles and Single Atoms in Commercial Carbon-Supported Platinum-Group Metal Catalysts

Remarkable NO oxidation on single supported platinum atoms

Our first-principles density functional theoretical modeling suggests that NO oxidation is feasible on fully oxidized single θ-Al2O3 supported platinum atoms via a modified Langmuir-Hinshelwood pathway. This is in contrast to the known decrease in NO oxidation activity of supported platinum with decreasing Pt particle size believed to be due to increased platinum oxidation. In order to validate...

Electrosynthesized Reduced Graphene Oxide-Supported Platinum, Platinum-Copper and Platinum-Nickel Nanoparticles on Carbon-Ceramic Electrode for Electrocatalytic Oxidation of Ethanol in Acidic Media

In this work, the electrocatalytic oxidation of ethanol was studied in acidic media at the wholly electrosynthesized nanocomposites: platinum and its alloys (copper and nickel) anoparticles/reduced graphene oxide on the carbon-ceramic electrode (Pt/rGO/CCE, Pt-Cu/rGO/CCE, and Pt-Ni/rGO/CCE electrocatalysts). The electrosynthesized nanocomposites were characterized by scan...

Sintering of Supported Metal Catalysts

Strong interactions in supported-metal catalysts.

Many commercially important catalysts consist of small metal particles dispersed on inorganic oxide surfaces. Although in most cases there is no significant interaction between the metal and the support, strong bonding can be demonstrated in a recently discovered class of supported-metal catalysts. These cases typically involve group VIII metals dispersed on transition metal oxides whose surfac...
