Cyclic Voltammetry Studies on Electrochemical Behavior of the Composite Ni-P+TiO₂ Electrocatalysts in Alkaline Solutions

Abstract:

Electrochemical characteristics of the composite Ni-P+TiO₂ electrocoatings with a differentiated content of TiO₂ composite component from 14 to 20 at.%, dependent on temperature conditions of electrodeposition from 293 to 333 K, was carried out in an alkaline 2.5 M NaOH solution. Cyclic voltammetry studies of the Ni-P+TiO₂ coatings and comparable Ni-P electrocatalysts revealed that cyclic cathode-anode polarization activated TiO₂ as the embedded composite component for the Ni-P+TiO₂ coating obtained at 333 K only.
