Anion adsorption, CO oxidation, and oxygen reduction reaction on a Au(100) surface: the pH effect

Article Abstract:

The effects of pH on the surface reconstruction of Au(100), on CO oxidation, and on the oxygen reduction reaction (ORR) are discussed by a combination of SXS, FTIR spectroscopy, and RRDE measurements. It is proposed that the pH-dependent kinetics of the ORR on Au(100) can be unraveled by finding the relationship between kinetic rates.

New insights for self-assembled monolayers of organothiols on Au(111) revealed by scanning tunneling microscopy

Article Abstract:

New information regarding self-assembled monolayers (SAMs) of organothiols on Au(111) at the molecular level is revealed by scanning tunneling microscopy (STM). A simple approach to modify interfacial properties in the design of organic molecular devices is provided by organothiol self-assembled monolayers (SAMs) on gold surfaces

Solvent organization above metal surfaces: Ordering of DMSO on Au

Article Abstract:

Scanning tunneling microscopy (STM) is utilized in situ to image the structures formed by neat dimethyl sulfoxide (DMSO) on Au surfaces at room temperature. The STM reveals that DMSO forms ordered arrays on Au(111) lattices but is substantively disordered on the new lower Miller index faces of Au.
