A Porous Tungsten Substrate for Catalytic Reduction of Hydrogen by Dealloying of a Tungsten–Rhenium Alloy in an Aqueous Solution of Hydrochloric Acid

open access: yesApplied Sciences, 2022
Selective dissolution of a tungsten (85 wt.%)–rhenium (15 wt.%) alloy with rhenium in hydrochloric acid at the temperature of 298 K and anodic polarization modes was carried out to develop a porous catalytic substrate and to recycle rare metals.

Impact of the type of anodic film formed and deposition time on the characteristics of porous anodic aluminium oxide films containing Ni metal [PDF]

open access: yes, 2011
Porous anodic films containing nickel were prepared by AC electro-deposition. The porosity of the films was controlled by using different working conditions (anodisation electrolyte, voltage, and time).

Electrochemical Oxidation of Formic Acid on the Surface of an Anodically Modifi ed Ag15Pd Alloy

open access: yesКонденсированные среды и межфазные границы, 2020
It was shown that the phase transformation of palladium into its own phase during the selective dissolution of the Ag15Pd alloy proceeds in the instantaneous nucleation mode and is limited by the surface diffusion of Pd ad-atoms to the growing three ...
