Anatase TiO2 colloidal dispersions were obtained by hydrothermal synthesis at 200 °C from titanium isopropoxide gels modified with acetic acid in the presence of a non-ionic surfactant. Absolute ethanol, anhydrous terpineol and ethyl cellulose added to this anatase dispersion resulting 23 wt% paste. Mesoporous films for application as working electrodes dye-sensitized solar cells prepared screen-printing method, yielding reproducible thicknesses about 10 μm desired porosity levels single...
Abstract This work presents the analytical method development for iron and copper determination in ethanol fuel. was developed using stripping voltammetry with a glassy carbon electrode modified Nafion/Carbon‐nanotubes. With linear sweep achieved limit of detection 7.1×10 −7 mol L −1 Fe 3+ 5.1×10 −8 Cu 2+ . The amperometric sensitivities were 2.0×10 6 µA 2.8×10 7 recovery study showed that has good accuracy repeatability, 108 103 % respectively.
The development of an effective cocatalyst for the modification TiO2 arrays has become highly desirable improvement their photoelectrocatalytic properties. We investigated with nickel-based cocatalysts (nickel (Ni0), nickel oxide (NiO), and sulphide (NiS)) by electrochemical deposition. formation n-p heterojunctions Ti/TiO2/NiO Ti/TiO2/NiS generation Schottky-type barrier Ti/TiO2/Ni0 led to enhancement visible light absorption reduction band gap energy, contributing significantly improving...
QCM TECHNIQUE.This article discusses the adsorption kinetics of a L-cysteine monolayer onto gold surface by means information obtained through technique.The results indicate that process is rapid and follows Langmuir isotherm, in which desorption are considered.From these measurements following parameter values were obtained: k d = (4.2± 0.4) x 10 -3 s -1 , 75 ± 6 M K eq =(1.8 0.3) 4 ΔG ads -(5.8± 0.2) kcal mol .
