Abstract Inverse oxide/metal model systems are frequently used to investigate catalytic structure-function relationships at an atomic level. By means of a novel layer deposition process, growth single-site Fe 1 O x on Pt(111) single crystal surface was achieved, as confirmed by scanning tunneling microscopy (STM). The redox properties the catalyst were characterized synchrotron radiation based ...

The preferential oxidation of CO (CO-PrOx) to CO2 is an effective catalytic process for purifying the H2 utilized in proton-exchange membrane fuel cells power generation. Our current work reports on synthesis, characterization and CO-PrOx performance evaluation unsubstituted magnesium-substituted iron- cobalt-based oxide catalysts (i.e., Fe3O4, Co3O4, MgFe2O4 MgCo2O4). More specifically, abilit...

Density functional theory calculations have been carried out to explore the effect of hydrogen on the oxidation of CO in relation to the preferential oxidation of CO in the presence of excess hydrogen (PROX). A range of gold surfaces have been selected including the (100), stepped (310) surfaces and diatomic rows on the (100) surface. These diatomic rows on Au(100) are very efficient in H-H bon...

The preferential CO oxidation (so-called CO-PROX) is the selective amid H2-rich atmospheres, a process where ceria-based materials are consolidated catalysts. This article aims to disentangle potential CO–H2 synergism under CO-PROX conditions on low-index ceria surfaces (111), (110) and (100). Polycrystalline ceria, nanorods nanocubes were prepared assess physicochemical features of targeted su...

The fundamental correlations between solubility and solvation structure for the electrolyte system comprising N-(ferrocenylmethyl)-N,N-dimethyl-N-ethylammonium bistrifluoromethylsulfonimide (Fc1N112-TFSI) dissolved in a ternary carbonate solvent mixture is analyzed using combined NMR relaxation and computational methods. Probing the evolution of the solvent−solvent, ion−solvent and ion−ion inte...

Here, metal nanoparticles were synthesized by chemical reduction of the corresponding metal salts in the presence of chitosan polymer. Binary and ternary metallic-chitosan Pt-Fe-CH, Pt-Co-CH and Pt-Fe-Co-CH nanocomposites were prepared. Transmission electron microscopy images and UV–Vis spectra of the nanocomposites confirmed the presence of the metal nanoparticles. The electrocatalytic activit...
