Facile fabrication of Zn/Zn-5(OH)(8)Cl-2 center dot H2O flower-like nanostructure on the surface of Zn coated with poly (N-methyl pyrrole)
Zn/Zn-5(OH)(8)Cl-2 center dot H2O flower-like nanostructures was electrodeposited on the coated Zn with poly (N-methyl pyrrole) in 0.1 M Zn (NO3)(2) and 0.1 M KCl solution. The morphology and the structure of the Zn/Zn-5(OH)(8)Cl-2 center dot H2O were characterized by Field Emission Scanning Electro...

| Summary: | Zn/Zn-5(OH)(8)Cl-2 center dot H2O flower-like nanostructures was electrodeposited on the coated Zn with poly (N-methyl pyrrole) in 0.1 M Zn (NO3)(2) and 0.1 M KCl solution. The morphology and the structure of the Zn/Zn-5(OH)(8)Cl-2 center dot H2O were characterized by Field Emission Scanning Electron Microscopy ( FESEM), Fourier transform infrared (FT-IR) spectroscopy and X-ray diffraction analysis (XRD). The FT-IR results showed special peaks at 908 and 728 cm(-1) related to Zn-5(OH)(8)Cl-2 center dot H2O. The FESEM results indicated that Zn/Zn-5(OH)(8)Cl-2 center dot H2O consists of a flower-like nanostructure and these flower- shaped structures contain many shaped nanopetals with the thickness of 27.8 nm. The XRD result confirmed that the major phase of electrodeposited product in 0.1 M KCl as supporting electrolyte was Zn-5(OH)(8)Cl-2 center dot H2O. The ability of PMPy to create a thin film and the existence of several pores in its matrix act as a mold for the growth of Zn/Zn-5(OH)(8)Cl-2 center dot H2O flower-like nanostructure. The trapping of Cl- and OH- within pores can be considered as the reason for the formation of flowerlike Zn/Zn-5(OH)(8)Cl-2 center dot H2O nanostructures in 0.1 M KCl. (C) 2011 Elsevier B.V.
