摘      要：The initial electrocrystallization of As-Sb alloy on glass carbon(GC)electrode in hydrochloric acid system was studiedvia cyclic voltammetry(CV)and chronoamperometry *** transients were presented in dimensionless formation,which showed that the initial nucleation/growth process of As-Sb alloy followed three-dimensional nucleation model with *** nucleation parameters were calculated by analyzing related current *** attention waspaid to the effect of Sb(III)concentration on the nucleation process during the *** quantitative results showedthat Sb(III)played a positive effect on enhancing the nucleation rate of As-Sb alloy,leading to the evolution of alloy surfacemorphology from grain structure to compact layer structure.
