Voltammetric study of electro-reduction of tetraamminepalladium(II) onto gold electrode

► Thermodynamic and spectrophotometric analysis of ammonia palladium(II) complexes solution. ► The palladium deposition from tetraamminepalladium(II) solution was indicated as a one-step 2-electrone process. ► The mechanism of tetraamminepalladium(II) complexes to metallic Pd was proposed. ► Using the voltammetry techniques the diffusion coefficient of [Pd(NH3)4]2+ was determined.
