A series of constant current anodizing processes in fluoride-free H3PO4 solutions, NH4F solutions of different concentrations (0.7 wt%, 0.5 wt% and 0.2 wt%), and different mixed electrolytes containing both NH4F and H3PO4, have been compared in detail.
Herein, in order to explore different morphology of anodic alumina film during a series of constant current anodization processes, NH4F solutions, H3PO4 solutions of different concentrations (2 wt%, 4 wt% and 6 wt%), and their mixed electrolytes containing different concentrations of NH4F and H3PO4 were employed.
The electrochemical behavior of sodium 12-tungestodicobaltoate, Co2W12O428− (CoTA), on glassy carbon electrodes (GCE) in aqueous and mixed solvent electrolytes containing 0.5 M H2SO4 has been studied.
The electrochemical activity of the Ce3+/4+reaction in the presence of various mixed acid electrolytes containing methanesulfonic acid (MSA) as the base electrolyte along with hydrochloric, nitric and sulfuric acid was investigated as a function of acid concentration and reaction temperature on a Pt disk electrode.
The addition of a single additive, 2- dimethylamino -pyridine, to the electrolyte containing an ionic salt, 1,2- dimethylamino -pyridinelium iodide, in the mixed solvent results in an enhancement of the cell performance.
An electrolyte containing ethanol was found to produce higher currents than electrolyte containing ammonium.
The polymer electrolyte containing 48 wt.
These have an anode made of carbon (usually graphite) a metal oxide cathode and an electrolyte containing lithium salt.
The polysulfide electrolyte contained 1 M Na2S and 1 M sulfur in a mixed solution of methanol and water with the volume ratio of 7 3.
