Abstract

The use of thermal knives as holding mechanism and non-explosive release in the field of space mechanisms has always been considered. In these mechanisms, the use of materials with high melting points and low weight, as well as the possibility of production on a small scale is a major challenge. Therefore, the use of platinum / alumina catalysts can be a good solution to the leading problems in this field.
The purpose of this paper is to prepare a high specific surface alumina base using the process of anodizing aluminum and coating it with platinum particles. Thus, the present study consists of two stages; In the first stage, aluminum is anodized in oxalic acid solution and its parameters are optimized in order to achieve aluminum nanotubes with various diameters and wall thicknesses, as well as the applied voltage, electrolyte concentration and anodizing conditions. In the next step, platinum nanoparticles were precipitated in different amounts using metal salt and suitable solvent using electrochemical method. The results showed that the obtained nanowires have a diameter of about 200 nm and a length of several micrometers. All samples were mechanically polished and it was shown that the aluminum anode oxide membranes were completely filled with a combination of metals. Also, the performed analyzes showed that the obtained nanowires are stable inside the membrane
