Abstract:
Electrochemical corrosion of a gold anode in a weakly basic aqueous solution of hexamethylenetetramine (urotropine) was studied in the galvanostatic mode at various currents. The formation of a compact gold deposit as dendrites on the cathode and colloidal gold nanoparticles in the electrolyte was detected by scanning and transmission electron microscopy. The kinetics of anode corrosion was studied by the gravimetric measurements of the loss in weight of the gold anode and the increase in the mass of the cathode over time. By cyclic voltammetry, it was shown that a gold—urotropine complex can be formed at the anode and subsequently migrate to the solution to be reduced at the cathode. After electrolysis, urotropine was isolated from the electrolyte in the unchanged form
