Kinetics of anodic layer formation on Gold

Active Intermediates in Plasmon-Induced Water Oxidation at Au Nanodimer Structures on a Single Crystal of TiO2

“…We observed simple pathways with a single intermediate in the plasmon-assisted water oxidation, especially in a neutral electrolyte. The novel pathways play a noticeable role in accelerating the OER by polarizing a rather small overpotential, compared with Au nanostructures on ITO glass or traditional bulk Au electrodes. − To the best of our knowledge, our work is the first identification of the intermediate species in plasmon-induced water oxidation, which provide prospects for designing more efficient water-splitting and photoelectric conversion systems.…”

Low-Copy Number Protein Detection by Electrode Nanogap-Enabled Dielectrophoretic Trapping for Surface-Enhanced Raman Spectroscopy and Electronic Measurements

“…11,34 Gold is, however, prone to corrosion especially in chloride-containing electrolytes, which include almost all biologically relevant buffers. 37,38 Chloride reduces the standard reduction potential of the Au/AuIII redox pair from 1.4 to 1.0 V, making gold less noble. 39 In the presence of oxygen, for example, nanogaps as used here will inevitably undergo crevice corrosion.…”

“…On the other hand, various nanoscale metallic structures found in the literature may serve as good SERS substrates, ,,, but to our knowledge none has been applied simultaneously as a mDEP molecular trap for active sample transport, particular for protein analysis . To be noted, many of the SERS substrates previously introduced were fabricated using gold. , Gold is, however, prone to corrosion especially in chloride-containing electrolytes, which include almost all biologically relevant buffers. , Chloride reduces the standard reduction potential of the Au/AuIII redox pair from 1.4 to 1.0 V, making gold less noble .
