摘要
The kinetics and mechanism of corrosion of an Au anode in a weakly basic aqueous solution of 2,2-dimethyl-1,3-diaminopropane (2,2-DM-1,3-DAP) were studied by gravimetry and cyclic voltammetry. Scanning and transmission electron microscopy was used to determine that under galvanostatic conditions the products of anode corrosion are reduced on a steel cathode with the formation of not only an electrolytic Au deposition on the cathode, but also colloidal gold nanoparticles in the electrolyte medium. The product of the interaction of 2,2-DM-1,3-DAP with atmospheric CO2, namely, the carbamic acid internal salt 3-ammonio-2,2-dimethyl-propylcarbamate, was isolated from the reaction solution.
