Prussian Blue Degradation during Hydrogen Peroxide Reduction: A Scanning Electrochemical Microscopy Study on the Role of the Hydroxide Ion and Hydroxyl Radical

“…, which can be easily produced in a friendly environment, SECM has been used to pattern different organic layers immobilized on various substrates by generating HO . from the Fenton reaction, by electrogenerating Ag 2+ , or by taking advantage of the specific properties of platinum …”

Development of a polystyrene sulfonate/silver nanocomposite with self-healing properties for biomaterial applications

“…Possible pathways of the silver reduction could thus be: autocatalytic light reduction [16] (although we tried to work in the dark as much as possible); reduction in contact with air/water; incomplete sulfonation of the polymer with remaining polystyrene groups, the latter of which can be oxidized [17]. The chemical reduction of the silver ions in the PSSAg nanocomposite by adding ascorbic acid yields silver nanoparticles of 160 AE 38 nm on average.…”

Parallel Imaging and Template‐Free Patterning of Self‐Assembled Monolayers with Soft Linear Microelectrode Arrays

“…[6,12] The pH shift associated with nitrite oxidation was applied in the local etching of a thin Ni coating on a gold substrate in a chemical lens. [13] Kanoufi et al reported the localized reduction of poly(tetrafluoroethylene) [14] and the oxidation of polystyrene [15] followed by further surface treatments. More recently, Hapiot et al discovered that transient hydroxyl radicals OHC can be used to remove organic coatings.…”
