dc.description.abstractNucleation and growth mechanisms (NGMs) of nickel(II) hexacyanoferrate, nickel(II) octacyanomolibdate, and copper(II) octacyanomolibdate were performed by means of the potential step technique by oxidizing the respective metal electrode in 0.02 M sulfuric acid containing the potassium salt of either hexacyanoferrate or octacyanomolibdate compounds. The obtained current-time transients (I/t) were analyzed using the theory of electrocrystallization of the metallic phase. As evidenced through these experiments, we can state that for the nickel cyanometalate compounds, electroformation takes place through a three-dimensional progressive NGM, and for the copper(II) octacyanomolibdate compound, electroformation occurs by means of a three-dimensional instantaneous NGM. The electrochemical results were verified through the use of atomic force microscopy (AFM). From these results, we can conclude that AFM is a good complementary technique to determine the nature of the NGMs through which electroformation of a solid phase occurs on an electrode surface.
