Surface Raman Spectra Obtained From Various Electrodeposited Transidon Metals, Jingsong Gao, Bin Ren, Qunjian Huang, Zhongqun Tian
Journal of Electrochemistry
Good quality potential-dependent surface Raman spectra of pyridine were obtained for the first time from a series of transition metals,e. g.,Fe,Co,Ni,Ru,Rh,Pd and Pt,which were electrodeposited on non-SERS-active substrates.The influences of the applied potential and the nature of metal on the adsorption behaviors were discussed briefly.This result illustrates that Raman spectroscopy is becoming a more general and powerful tool to study various electrochemical interfaces.

In Situ Studies Of Copper Electrodepostion On Hopg By Using Ecstm, Zhaoxiong Xie, Bingwei Mao, Xiangdong Zhuo, Jiqian Mu, Zhaowu Tian
Journal of Electrochemistry
In this paper, copper electrodepostion on HOPG had been in situ studied by using a homebuilt electrochemical scanning tunneling microscopy (ECSTM). Three dimensional nucleation and subsequent growth of copper crystals were found as the initial stage of copper deposition on HOPG. In the case of lower overpotential or lower concentration of Cu 2+ , the bulk deposited copper layer tended to form smooth terraces, and grow at the edge of steps. The terraces were stable to some extent, which made it possible to be observed with atomic resolution. At a higher overpotential, the crystal size of copper were somehow smaller. …

Journal of Electrochemistry
The electric conductivities of ZnCl 2 Urea melts were determined.The influences of temperature and concentration on the conductance have been studied.The cylic voltammetry,potentiostatic electrolysis and open circuit potential time curve after electrolysis,X ray diffraction were used to investigate the electroreduction of Zn 2+ , electrodeposition of zinc on some electrodes in urea metal chlorides melt. The conductivity of urea NaCl ZnCl 2 melt can reach to over 30 ms·cm -1 (125 ℃), and has a liner relationship with temperature from 108 to 140 ℃. The electroreduction of Zn 2+ to zinc is reversible at one step, and CuZn 5 alloy …
