Synthesis of nickel coatings with high surface area on the ceramic powders

Abstract

The study of the dynamic of the synthesis processes of nickel nanostructured coatings on the ceramic powders is presented. It has used the approach with the minimal set of reagents for the deposition of nickel coatings with high surface area. The Al2O3 is selected as a ceramic powder. As a result of the study, it has found the optimal conditions for the synthesis of Ni/Al2O3 composite powders with high surface area. It has studied the dynamic of the synthesis process of nickel coating by the scanning electron microscopy that allowed us to clarify the mechanism of the synthesis of nickel nanostructured coatings. The surface area of the synthesized composite powders was studied by nitrogen adsorption. The obtained results may have wide applications in catalysis and electrochemistry.
