Anodizing of Magnesium Alloy Az31 by Alkaline Solution

-Anodizing of AZ 31 Mg alloy was investigate in 3M KOH solution for 10, 20 and 30min. at constant voltage of 5V. Atomic force microscope (AFM) used to investigate the roughness of anodic film formed on the surface while the scanning electron microscope (SEM) was used to determine the morphology of the anodic film, it was found that the roughness of the anodic film is mainly depend on the anodiz...

In situ activation of a Ni catalyst with Mo ion for hydrogen evolution reaction in alkaline solution

In this study Ni catalyst have been activated during hydrogen evolution reaction (HER) by adding Mo ions into the alkaline electrolyte. After dissolving different amounts of ammonium molybdate in the 1M NaOH as electrolyte, Ni catalyst was used as cathode for HER. Afterwards a comparison between hydrogen overpotential measured in Ni catalyst with and without in situ activation has been made; th...

Evolution Reaction in Aqueous Alkaline Solution Hydrous Nickel Oxide: Redox Switching and the Oxygen

Effect of temperature on kinetics of the hydrogen evolution reaction on Ni-P-C cathodes in alkaline solution

The kinetics of hydrogen evolution reaction (HER) was studied in 1M NaOH at various temperatures (298 to 358 K) on Ni-P-C (composite electrodes. The electrochemical efficiency of the electrodes has been evaluated on the basis of electrochemical data obtained from the steady-state polarization Tafel curves, electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) in 1M NaOH solut...

Experimental investigation on synthesis of merlinoite and gismondine zeolites by lithium alkaline solution under hydrothermal condition

This research was carried out to study hydrothermal synthesis of merlinoite and gismondine zeolites from perlite, as the raw material for the production of essential silica and aluminum, under alkaline condition, at a constant temperature of 150˚C during 3 days. All experiments were performed on the same sample of perlite powder without any purification and all reactions were carried out into t...
