“…After the maximum value, the experimental curve was slightly deviated from the standard curve, which might be caused by partial kinetic control of the growth. 16 For the transients of pH 11 solution, the experimental curve was in good agreement with the theoretical curve of instantaneous nucleation growth mechanism before maximum value. This means all crystal nucleus were appeared at one time and less complex nanostructure might be obtained.…”

Two kinds of dendritic Te crystals were successfully prepared by electrodepositing TeO 2 in pH = 3, 8 and 11 solutions respectively. The parameter of pH played an important role in growth rate. Moreover, the nucleation of Te in pH = 3 and 8 solutions were conformed to progressive type while in pH = 11 solution was conformed to instantaneous type. By systematically studying the morphologies evolution of Te crystals with different deposition times in pH = 3, 8 and 11 solutions, the structure of crystal was confirmed directly decided by nucleation type. Base on this, a growth mechanism for two kinds of dendritic crystals was proposed. Moreover, this mechanism may provide a reference for predicting the morphology of Te crystals in electrodeposition process.Electrodeposition of an element on a foreign substrate involving two processes: the nucleation of a new solid phase and its subsequent growth. The nucleation process can directly influence the morphology of deposit, and the morphology decided the physico-chemical properties of deposit. However, how the nucleation influence the morphology of deposit is rarely studied in previous studies. Te is an important element semiconductor with high anisotropy properties which means its morphology would be highly depend on nucleation state and growth rate. However, to date, Te is rarely prepared by electrodeposition technique and the nucleation in deposition process is rarely studied as well. Streltsov and his coworker studied the nucleation of TeO 2 deposit on n-and p-Si (100) wafers respectively, but the influence of nucleation to final morphology is not involved. 1 In this work, TeO 2 was deposited on polyimide/reduced graphene oxide electrode (PI/rGO). According to a series study of nucleation and morphology of Te in different pH solutions, we have an initial comprehension of how nucleation influences the morphology of deposit. Moreover, the active site of PI/rGO electrode is the exposed rGO, therefore, the nucleation of Te on PI/rGO electrode could be seen as the nucleation of Te on rGO film. In recent years, graphene and its derivative have been wide employed to modify electrode, so this study may offer a reference for nucleation on graphene material.In this work, two kinds of dendritic Te crystals were obtained. Among various nanostructures, material with dendritic shape has attracted more and more attentions for its special nanostructure offering material many potential applications in catalytic, biosensor and so on. 2,3 Te is a p-type semiconductor has potential applications in electric/optical devices, thermoelectric devices, gas sensor and so on. 4,5 For the highly anisotropic property, Te crystals has numerous structures. 6,7 To date, almost all Te crystals with dendritic structure were prepared by hydrothermal method. 8-10 However, in hydrothermal method various surfactants were added which always with poisonousness. Therefore, fabricating dendritic Te crystal by an environment friendly electrochemistry method is an interesting topic. It is well known that nanostru...

“…With the increase of deposition potential, the current transient curve approaches closer the limit for 3D instantaneous nucleation and growth. Such a potential dependence also occurred in the electrodeposition of copper on Au(1 1 1) [57], silver on different carbon substrates [58], and bismuth on fluorine-doped tin oxidecoated conducting glass substrates [44].

“…Each curve displays a couple of well-defined cathodic and anodic peaks and a crossover between the cathodic and anodic branches. Same CV shapes can be found in two related papers [31,44]. Usually, the deposition potential of metallic ions on a foreign substrate is higher than the deposition potential on the electrode made of the same metal due to a nucleation overvoltage; in the anodic direction, however, the oxidation of metal starts from the surface that already has metal deposited, resulting a potential close to the metal/metal ion equilibrium potential [47].…”

“…Electrochemical techniques such as cyclic voltammetry (CV) and chronoamperometry (CA) played a dual role: first, serving as the methods for metal deposition, and second, being used as diagnostic tools for the determination of reaction mechanisms [44,47]. To extract kinetic parameters from the experimental CA data, the Scharifker general equation [48] and the Heerman-Tarallo equation [49] were widely used.…”

“…The forward and reverse current traces of the CVs are seen to cross over in the region of minus0.1 V indicating the presence of a 'nucleation loop' [29,30]. Nucleation loops are observed as bismuth nucleation has to occur on the electrode surface before bulk deposition can take place resulting in a delay in the reduction current.…”
