Textural Characteristics of Products Obtained by Electrochemical Oxidation of Copper and Cadmium Using Alternating Current

Abstract:

The porous structures of nanoparticles of copper and cadmium prepared by AC electrochemical synthesis in solutions of acetate of sodium, chlorides of ammonium and sodium were studied. It is established that at current density of 1A/cm² and concentration of NaCl 3 % wt. with the highest specific surface area (8.23m²/g), maximum pore volume (0.029 cm³/g) are formed, and the largest volume of the particles is characteristic of the nominal pore diameter - 62 nm. The values of specific surface area and total pore volume with increase in the temperature of calcination decrease, and the pores are slightly enlarged in diameter. Thus, the obtained data allow predicting operating parameters of the electrolysis to obtain copper - cadmium oxide system a predetermined porous structure.
