“…The parameters that play the role on electrophoretic deposition are composition of dispersion medium, pH of electrolyte, and concentrations of particles and electrolyte. The principles behind electrolytic deposition and electrophoretic deposition have been studied [49][50][51]. An understanding about these two processes is required in order to fabricate desired electrode material.…”

The transition metal oxide has been recognized as one of the promising electrode materials for electrochemical capacitor application. Due to the participation of charge transfer reactions, the capacitance offered by transition metal oxide can be higher compared to double layer capacitance. The investigation on hydrous ruthenium oxide has revealed the surface redox reactions that contributed to the wide potential window shown on cyclic voltammetry curve. Although the performance of ruthenium oxide is impressive, its toxicity has limited itself from commercial application. Manganese oxide is a pseudocapacitive material behaves similar to ruthenium oxide. It consists of various oxidation states which allow the occurrence of redox reactions. It is also environmental friendly, low cost, and natural abundant. The charge storage of manganese oxide film takes into account of the redox reactions between Mn 3+ and Mn 4+ and can be accounted to two mechanisms. The first one involves the intercalation/deintercalation of electrolyte ions and/or protons upon reduction/oxidation processes. The second contributor for the charge storage is due to the surface adsorption of electrolyte ions on the electrode surface.

“…As the oxidation process can lead to the dissolution of metal substrate, the cathodic reduction is usually preferred over anodic oxidation as various metals can be employed as the substrates [51]. 2+ to MnO 2 in the medium with different acidity is described in Section 4 [54,55].…”

En el presente trabajo se analiza el proceso de crecimiento mediante electrodeposición, de columnas de ZnO sobre un sustrato de vidrio recubierto de óxido de estaño y fluor (FTO). Hemos determinado una ley de crecimiento de las columnas, de tipo exponencial, que relaciona la altura de éstas con el tiempo de exposición. Se observa que para tiempos de exposición inferiores a 10 3 s, manteniendo constante la temperatura (65±2 ºC) y la densidad de corriente (i = 2,5 mA/ cm 2 ), las columnas crecen de acuerdo a una ley de tipo exponencial; para tiempos de exposición superiores a 10 3 no se cumple necesariamente esta ley. Se analizan los espectros de fotoluminiscencia de las muestras a la temperatura ambiente (300 K) y a baja temperatura (19K). Se observa, también, que los distintos espectros de fotoluminiscencia están relacionados con el crecimiento y ramificado de las columnas. Palabras clave: Electrodeposición, fotoluminiscencia, SEM, AFM. ZnO columns obtaining. Variables to control (and II)The growth process via electrodeposition technique, of zinc oxide (ZnO) columns, on a glass substrate coated with conductor tin oxide and fluorine (FTO), is analysed. An exponential law of columns growth is determined to relate the columns height with exposition time in electrolytic mean. The columns growing is governed by an exponential law for electrolytic exposition times under 10 3 s, with constant temperature (65±2 ºC) and current density (i = 2,5 mA/ cm 2 ); for exposition times larger than10 3 seconds this law is not necessary fulfilled. The specimen photoluminescence spectra at room temperature (300 K) and at low temperature (19 K) are analysed too. We also notice the photoluminescence spectra are related to the columns growing and branching.

“…1d). Various methods such as hydrothermal synthesis, 22 sol-gel method, 23 electrostatic spray deposition, 24 electrophoretic deposition, 25 anodic oxidation, 26 and cathodic reduction 27 have been reported for making MnO 2 . Among them, electrodeposition 26,27 is attractive because it forms conductive paths to every MnO 2 particle.…”
