Electrochemical Synthesis of CdS on Multi Walled Carbon Nanotubes Paste Electrode

Abstract:

CdS has been synthesized electrochemically on multi walled carbon nanotubes paste electrode (MWCNPE) from aqueous solutions consists of Cd²⁺ and S₂O₃^2- at40°C, using potentiostatic technique.Cyclic voltammetric response of thiosulfateand Cd²⁺ individually and together has been investigated. The optimum conditions of CdS electrodeposition were determined. Interesting data were obtained and discussed in this work. The mechanism of CdS electrodeposition was suggested. Moreover, the electrodeposited CdS is of n-type semiconductor. Ithas been investigated by the Mott-Schotky test, and also the concentrations of donors (N_D) were determined.
