| Abstract | Na2MoO4 electrochem. redn. from 0.22 mol/dm3 sodium citrate supporting soln. was investigated by the cyclic voltammetry, XPS and lateral force microscopy techniques. Exptl. results have indicated that molybdenum oxide is initially deposited on the Se/SnO2/glass surface in a potential range from -0.20 V to -0.80 V. XPS anal. exhibited the molybdenum oxide stoichiometry of 2.9. The nucleation mechanism of MoOx onto Se/SnO2/glass surface was investigated by the current transient technique. The deposition transients analyzed in the non-dimensional plots I2/I2m = f(t/tm) and I2/I2m = f(t/tm)2 have shown that MoOx nucleates according to a progressive mechanism. The nucleation rate depends on Na2MoO4 concn. in the supporting electrolyte and on the deposition potential. [on SciFinder(R)] |
