Cyclic voltammetry and chronopotentiometric and chronoamperometric curves were used to study the electroreduction of Lu3+ in a LiCl +DMSO system. The electrode process of Lu3+ reduced on a Pt electrode occurs in one step: Lu3++3e-Lu. The transfer coefficient and diffusion coefficient of Lu3+ in the 0.1mol dm3 LuCl3+0.1 mol dm3 LiCl+DMSO system were calculated as 0.141 and 2.86

摘要

Deposition of Yb Bi thin films was carried out from a nonaqueous solution by using cyclic electrodepositon. During electrodeposition the substrate potential was continuously cycled between two potentials. The effects of several factors including the potential of deposition, time of deposition and sweep rate on the Yb content in the thin films and surface morphology were studied. Experimental results indicate that the amorphous Yb Bi thin films containing Yb 2104%～36.36 % (mass fraction) can be prepared in 0.10mol•L-1 YbCl3+0.10mol•L-1Bi (NO3) 3+0.10mol•L-1LiCl+DM2SO by controlling deposition conditions of the system. They are black, uniform, metallic luster and adhered firmly to the copper substrates. The films were characterized by X ray energy dispersive analysis (EDS), scanning electron microcoscope (SEM) and X ray diffraction (XRD).

摘要

利用循环伏安法研究了膦硫混配原子簇化合物Co6S8[OCH3)3]6的电化学行为，结果表明Co6S8[OCH3)3]6在CH2Cl2溶液中可观察到三个可逆氧化还原过程，其电子转移过程为：Co6S8[P(OCH3)3]6-e+eCo6S8[P(OCH3)3]60-e+eCo6S8[P(OCH3)3]6+-e+eCo6S8[P(OCH3)3]62+并探讨了其电子转移的机理和结构构型的关系以及作为电子贮存分子器件的可能性。
