“…Furthermore, evidence for the formation of Bi I[31] during the anodic oxidation of Bi was presented . The electrodeposition of bismuth from a 1:2 mixture of choline chloride/urea containing Bi 2 O 3 was studied, and the electrodeposition of films of Bi, Te, and thermoelectric BiTe from choline chloride/malonic acid and from choline chloride/oxalic acid was also explored . Moreover, the electrodeposition of films of BiTeSe from choline chloride DESs with ethylene glycol, malonic acid, or oxalic acid and the electrodeposition of films of BiSe from choline chloride/malonic acid was demonstrated.…”

Tin, Bismuth, and Tin–Bismuth Alloy Electrodeposition from Chlorometalate Salts in Deep Eutectic Solvents

The electrodeposition of tin, bismuth, and tin–bismuth alloys from SnII and BiIII chlorometalate salts in the choline chloride/ethylene glycol (1:2 molar ratio) deep eutectic solvent was studied on glassy carbon and gold by cyclic voltammetry, rotating disc voltammetry, and chronoamperometry. The SnII‐containing electrolyte showed one voltammetric redox process corresponding to SnII/Sn0. The diffusion coefficient of [SnCl3]−, detected as the dominating species by Raman spectroscopy, was determined from Levich and Cottrell analyses. The BiIII‐containing electrolyte showed two voltammetric reduction processes, both attributed to BiIII/Bi0. Dimensionless current/time transients revealed that the electrodeposition of both Sn and Bi on glassy carbon proceeded by 3D‐progressive nucleation at a low overpotential and changed to instantaneous at higher overpotentials. The nucleation rate of Bi on glassy carbon was considerably smaller than that of Sn. Elemental Sn and Bi were electrodeposited on Au‐coated glass slides from their respective salt solutions, as were Sn–Bi alloys from a 2:1 SnII/BiIII solution. The biphasic Sn–Bi alloys changed from a Bi‐rich composition to a Sn‐rich composition by making the deposition potential more negative.

The electrochemical and sonoelectrochemical synthesis of polypyrrole (PPy) on St-12 steel was achieved in an oxalic acid medium by using a galvanostatic method with a current density of 4 mA/cm 2 . Direct application of low-frequency ultrasound led to more compact and more homogeneous surface structures for PPy. The corrosion behavior of the coatings was studied through open circuit potential-time curves, potentiodynamic polarization technique, and electrochemical impedance spectroscopy measurements in NaCl 3.5% solution. The Kramers-Kronig transformations were applied to evaluate the validity of the impedance data. The results showed that the coating resistance (R coat ), corrosion resistance (R corr ), and warburge resistance of ultrasonically prepared samples were higher than that of nonultrasonically synthesized PPy. With the help of scanning electron microscopy, we investigated the effects of the ultrasonic irradiation on the morphology and the results reveal that the sonoelectrochemical synthesis method yielded strongly adherent and smooth coats.
