“…In this context, scanning electrochemical microscopy (SECM) is a powerful tool to study PB materials; it was already used to map PB deposition at macrometer and micrometer scales and to draw patterns of PB analogues by precipitation on a gold substrate . It was also shown that the SECM ultramicroelectrode (UME) can be modified by PB or PB analogues to engineer microsensors, which were used to map H 2 O 2 production at a Pt UME …”

The degradation of Prussian blue (PB) during H2O2 reduction is investigated by scanning electrochemical microscopy (SECM). Coupling SECM with optical microscopy allows quantitative assessment in situ of the effect of HO− on the dissolution of PB in lithographic experiments. The local production of HO− in the vicinity of PB is an easy way to pattern a PB layer; Such PB dissolution during H2O2 reduction leads to the release of soluble ferrocyanide and Fe2+. In the presence of H2O2, the latter initiate the Fenton reaction and the generation of highly reactive hydroxyl radicals HO.. This is revealed by the degradation of an organic layer immobilized on an ultramicroelectrode held in the vicinity of a PB layer during H2O2 reduction. The formation of such reactive species is of great importance to further understand the possible origin of the activity loss of sensors, batteries, and photovoltaic cells when composite materials based on PB or on its derivatives are used as catalysts for H2O2 or O2 reduction.

“…Xia and coworkers demonstrated that PB could deposit directly on semiconductor (for example, TiO 2 and Si) surfaces via photocatalytic deposition or galvanic displacement from a ferricyanide or ferric ions containing solution910. Based on the photocatalytic property and their unique architectural morphology1112, anodically grown TiO 2 nanotube arrays (TiNTs) can be a promising supporting electrode material in construction of electrochemical biosensors because the anodic TiNTs are grown directly on a titanium-metal substrate.…”

Amperometric biosensors consisting of oxidase and peroxidase have attracted great attention because of their wide application. The current work demonstrates a novel approach to construct an enzymatic biosensor based on TiO2 nanotube arrays (TiNTs) as a supporting electrode on which Prussian Blue (PB)-an “artificial enzyme peroxidase” and enzyme glucose oxidase (GOx) have been immobilized. For this, PB nanocrystals are deposited onto the nanotube wall photocatalytically using the intrinsic photocatalytical property of TiO2, and the GOx/AuNPs nanobiocomposites are subsequently immobilized into the nanotubes via the electrodeposition of polymer. The resulting electrode exhibits a fast response, wide linear range, and good stability for glucose sensing. The sensitivity of the sensor is as high as 248 mA M−1 cm−2, and the detection limit is about 3.2 μM. These findings demonstrate a promising strategy to integrate enzymes and TiNTs, which could provide an analytical access to a large group of enzymes for bioelectrochemical applications including biosensors and biofuel cells.

“…SECM is a well-established technique with a key advantage of localizing and detecting interfacial electrochemical reactions [5] and has been widely employed to detect H 2 O 2 produced by the oxygen reduction reaction (ORR) on various solid substrates [6][7][8]. In this work, the water/DCE interface was formed between a DCE droplet containing DMFc supported on a solid electrode and immersed in an acidic aqueous solution.…”

a b s t r a c tScanning electrochemical microscopy (SECM) was used to monitor in situ hydrogen peroxide (H 2 O 2 ) produced at a polarized water/1,2-dichloroethane (DCE) interface. The water/DCE interface was formed between a DCE droplet containing decamethylferrocene (DMFc) supported on a solid electrode and an acidic aqueous solution. H 2 O 2 was generated by reducing oxygen with DMFc at the water/DCE interface, and was detected with a SECM tip positioned in the vicinity of the interface using a substrate generation/ tip collection mode. This work shows unambiguously how the H 2 O 2 generation depends on the polarization of the liquid/liquid interface, and how proton-coupled electron transfer reactions can be controlled at liquid/liquid interfaces.
