Water-Assisted Growth of Cobalt Oxide and Cobalt Hydroxide Overlayers on the Pt3Co(111) Surface

Bimetallic platinum–cobalt (Pt–Co) catalysts have highly enhanced performance for the oxygen reduction reaction (ORR), where this peculiar surface alloy structure contributes to efficient energy

In-situ X-ray absorption study of evolution of oxidation states and structure of cobalt in Co and CoPt bimetallic nanoparticles (4 nm) under reducing (H2) and oxidizing (O2) environments.

TLDR
The findings permit the prediction of the cobalt oxidation states as the reaction conditions are altered and suggest the presence of tetrahedral structure of Cobalt oxide that differs from the Co(3)O(4) spinel structure.

Structure sensitivity of CO oxidation on Co3O4: a DFT study.

TLDR
The results indicate that the U value can affect the calculated energetic result significantly, not only the absolute adsorption energy but also the trend in adsorptive energy.

Highly Ordered Mesoporous Cobalt-Containing Oxides: Structure, Catalytic Properties, and Active Sites in Oxidation of Carbon Monoxide.

TLDR
It is suggested that the octahedrally coordinated Co(2+) species is easily oxidized and shows high catalytic activity for CO oxidation.

Controlled vapor-phase synthesis of cobalt oxide nanomaterials with tuned composition and spatial organization

Cobalt oxide nanostructures are deposited by Chemical Vapor Deposition (CVD) on Si(100) substrates at temperatures between 300 and 550 °C, using for the first time a novel Co(II) adduct as molecular

Oxalato complexes of Pd(II) with Co(II) and Ni(II) as single-source precursors for bimetallic nanoalloys

The single-source precursors of noble–ignoble nanoalloys are of a great interest since they can be used in many areas such as optical, biomedical, catalysis, magnetic and chemosensors. The new

Mechanistic Aspects of Wet and Dry CO Oxidation on Co3O4 Nanorod Surfaces: A NAP-UPS Study

TLDR
This study focuses on the comparative CO oxidation rate on Co3O4 NR surfaces and highlights the changes in the electronic structure that occur in the catalyst during the CO oxidation reaction.
