Energy-dispersive x-ray spectroscopy (EDS) and x-ray diffraction (XRD) analyses of the deposits were also conducted to confirm the analysis of the reduction processes. The results show that, when MWNTs were added into each solution, the shape and number of peaks on each voltammogram remained unchanged, but the reduction peaks all shifted positively, and the peak current of each reduction peak increased slightly. The variation trends of the Nyquist plots in each system did not change with the addition of MWNTs. However, the same process occurred at more positive potentials, and the radius of the semicircle decreased at the same potentials compared with blank solutions. All these results indicate that addition of MWNTs into these electrolytes did not change the electrochemical reduction mechanisms of Bi3+, HTeO 2 + , and their mixtures, but let the reduction processes of Bi3+, HTeO 2 + , and their mixtures become easier. The results reveal that the presence of MWNTs can promote electrodeposition of Bi x Te y compound.
