Kinetics of electrolysis of transition-metal hexacyanide films and reduction of silver ferricyanide

Enzymatically induced formation of neodymium hexacyanoferrate nanoparticles on the glucose oxidase/chitosan modified glass carbon electrode for the detection of glucose

“…3 showed that the cathodic and anodic peak currents increase linearly with the increase of square root rates, suggesting the electrochemical reaction of NdHCF NPs formed on electrode surface was not a surface-controlled process but a diffusion-controlled one at the time of reaching the peak potential (Ayers and Piggs, 1971). This phenomenon has been confirmed by Moon et al (1993) and described as electrolytic conduction. Here, it is indeed only the diffusion of K + in the NdHCF lattice, and not in the solution, which can be rate determining when the solution concentration is 0.5 M, and the bulk diffusion is not rate determined.…”

Filmes de metal-hexacianoferrato: uma ferramenta em química analítica

“…Desde o primeiro trabalho versando sobre o PB modificando superfícies de eletrodos 2 tem havido um maior interesse na preparação eletroquímica, bem como, propriedades eletrocrômicas, eletrocatalítica ou caracterização espectroscópica do PB e seus análogos [3][4][5][6][7][8][9][10][11][12][13][14] . Férrico-ferrocianeto 12,[15][16][17][18] e seus análogos (substituídos com Cu 19 , Ni 20 , Co 21 , Ru+In 22 , Mo 23 , V 24 , etc.)…”

EDL structure and peculiarities of ferricyanide cyclic voltammetry for silver deposits on gold

“…3). As it was mentioned above, the surface of the silver electrode in K 3 Fe(CN) 6 solution is covered with AgHCF(II) film [8,9]. The currents of C2 and A2 peaks depend linearly on the scan rate.…”

“…Meanwhile, Fe(CN) 6 3 − was shown to react with metallic Ag forming silver hexacyanoferrate (II) film (AgHCF(II)) [8,9]. This may cause an ambiguous interpretation of the results.…”
