A new method for electrocatalytic oxidation of ascorbic acid at the Cu(II) zeolite-modified electrode

Direct synthesis of Fe-ZSM-5 zeolite and its prospects as efficient electrode material in methanol fuel cell

“…The unique properties of zeolites (such as size, shape and charge selectivity) have been utilized for developing gas-sensors, voltammetric/amperometric and ion selective membrane electrodes [8][9][10]. Zeolitemodified electrodes for electrochemical reactions achieve an amplified response based on the synergistic properties of the constituents [11][12][13] in terms of increased current density.…”

Zeolite Nanoparticle Modified Carbon Paste Electrode as a Biosensor for Simultaneous Determination of Dopamine and Tryptophan

“…[27][28][29][30] In particular, substantial efforts have been devoted to the development of voltammetric biosensors based on ZMEs. [31][32][33][34][35][36] This article (at continuing our study on biological molecules [37][38][39][40][41][42][43][44][45][46] ) is an attempt to study the electrochemical behavior of iron(III) incorporated in ZCME and the application of a modified electrode for simultaneous determination of DA and Trp. This work is a new report on the application of Fe 3+ Y/ZCME for the determination of these compounds.…”

Mathematical modeling and experimental study of electrode processes

“…SPE was rinsed thoroughly with distilled water. They were used as it is ΔG°Free Gibbs energy of nanoparticles c 4,592 J mol −1 a Diffusion coefficient is taken as intermediate magnitude between 1.028×10 −5 and 3.39×10 −5 cm 2 s −1 given in [19] and [20] b Standard ox/red potential is calculated for pH=3, using the magnitude E°=0.18 V given in [21] for pH=7 c ΔG°for nanoparticles size equal to 8 nm is calculated with the use of formula (14) from [23] Calculation parameters: k chem =4×10 9 , r NO2 =0 (a), k chem = 0, r NO2 =0 (b), k chem =0, r NO2 =149 pm (c). Other parameters are given in Table 1 Fig .…”
