Morphology and Structure of Electrolytically Synthesized Tin Dendritic Nanostructures

The formation of tin dendritic nanostructures by electrolysis from the alkaline electrolyte has been investigated. Morphology and structure Sn dendrites produced applying both potentiostatic galvanostatic regimes are characterized SEM XRD, respectively. Depending on applied cathodic potentials, three types were obtained: (a) needle-like spear-like, (b) fern-like, (c) stem-like dendrites. very branchy with branches prismatic shape obtained regime represented a novel type dendrites, not previously reported in literature. To explain various forms, correlation polarization characteristics for this electrodeposition system is considered. spear-like monocrystals (200),(400) preferred orientation, fern-like exhibited predominant (220),(440) while particles crystallites oriented to greater extent (440) crystal plane than other planes. galvanostatically synthesized possessed strong orientation. influence parameters structural explained fundamental laws electrocrystallization taking into consideration concept slow-growing fast-growing
