N2  - The kinetics of the electrodeposition of CdTe from an aqueous solution containing CdSO4, TeO2 and H2SO4 were investigated by using a rotating ring-disc electrode. The results for tellurium deposition alone indicated that the reaction occurs through a six-electron reduction of HTeO2+ to H2Te, followed by a reaction between H,2Te and HTeO2+ yielding tellurium. At HTeO2+ concentrations greater than 10-3 M, the second step of this process is very fast and the overall reaction behaves as a four-electron reduction of HTeO2+ to Te: only at lower HTeO2+ concentrations was evidence observed for the six-electron reduction. The electrodeposition of CdTe occurs through two possible pathways: Cd2+ ions can react with H2Te produced during the reduction of HTeO2+ and thus yield CdTe, or tellurium deposited on the electrode can react with Cd2+ to yield CdTe. The two reactions compete with the deposition of pure tellurium. Conditions to deposit stoichiometric CdTe are suggested.
