“…5e, demonstrating a diffusion-controlled technique for the electrochemical oxidation of Ad on the surface of C–Co–N@MWCNTs/GCE. 36 In addition, the potential and logarithm of ν (ln ν ) exhibited a good linear relationship ( E p = 0.08 ln ν + 0.072). The number of transferred electrons was evaluated via the following equations: 40 where the gas constant, temperature, Faraday constant, and transfer coefficient are represented by R , T , F , and α, respectively.…”

“…Moreover, acidic media is not uncommon for adrenaline detection. 1,[46][47][48][49][50] Therefore, pH 4 of electrolyte was chosen for all electrochemical adrenaline sensing studies with La 2 CuO 4 /CPE. Figures 5D-5F represent the CV curves of electrocatalytic kinetic performance of the La 2 CuO 4 /CPE surface under various scan rates towards of the adrenaline oxidation at pH 4.…”

Electrochemical sensing is an excellent analytical means with multiple applications. Most of the electrochemical developments are based on the novel electrochemically active substrates. A lot of them have been adopted from other fields of material science. Every new class of functional materials has affected the development of electroanalytical chemistry. In this view, lanthanide cuprates, well-recognized high-temperature superconducting materials were considered for adrenaline sensing. Obtained from corresponding oxides, a highly crystalline La2CuO4 found to be a suitable substrate for analytical method development. It inherited sponge-like morphology common for the most of the previously reported lanthanum cuprates with narrow pore size distribution at 400-700 nm. Excellent charge mobility and low resistivity provided a carbon paste electrode with improved linearity range and low limit of detection. Repeatability and stability of the developed sensor were at a satisfactory level. Sensor functionality was verified on the real samples with excellent recovery rates. With this work we suggest further development of electroanalytical methods with application of lanthanide cuprates.

“…A signicant number of POM-based ECSs are mainly based on the redox reactions of target substances. 46,52,[61][62][63] Specically, when the analyte is in contact with a POM-based ECS, if the target is reductive, it will lose electrons on the electrode surface and be oxidized. Conversely, if the target substance is oxidizing, it will gain electrons on the electrode surface and be reduced.…”
