RESUMO:

The present work consists of three chapters that correspond to three scientific articles with different approaches and related topics. The first is a literature review article that addresses different forms of synthesis of iron-based and zinc-based metal oxides that are applied in catalysis. In addition to addressing the possibility of metal oxide formation by the cathodic cage plasma deposition method. The work emphasizes the possibility of producing metallic oxides by the cathodic cage method, for catalysis applications. The second article deals with the formation of iron oxide, hematite, in the alpha phase on 304 stainless steel and glass substrates. The oxide growth occurred in the film morphology using the cathodic cage plasma deposition method with the application of a carbon steel cage. In this work, studies of structural, morphological, electrochemical and thermo-optical properties of the films were carried out. The third article deals with the formation of zinc oxide film on the surface of 304 stainless steel, also using a cathodic cage deposition method applying a galvanized steel cage. The films produced under different treatment conditions had microstructural and morphological, mechanical and compositional characterization. That said, the work was able to confirm that the method of production of different films is effective and the films produced can be used for catalysis studies.
