对含有高浓度果糖的电解质进行了系统的电化学研究。利用瓦尔登法则和速率过程理论，测定和分析了果糖浓度对电解质粘度和电导率的影响。根据固定电极上循环伏安图的峰值电流和旋转电极上的极限电流计算了质子和铜阳离子的扩散速率。利用拉曼光谱表征了水中的氢键网络以及果糖浓度对该网络的影响。在旋转圆盘电极上研究了不同果糖浓度下铼的沉积。利用x射线荧光、x射线衍射和低温四点探针测量分别研究了薄膜的沉积速率、晶体结构和超导性。
A systematic electrochemical study is carried out on electrolytes with superhigh concentrations of fructose. The effect of fructose concentration on the viscosity and conductivity of electrolyte are determined and analyzed using Walden rule and the theory of rate process. The diffusion rates of proton and cupric cation are calculated from the peak current in cyclic voltammogram on stationary electrode and the limiting current on rotating electrodes. Raman spectroscopy is used to characterize the hydrogen bond network in water and the effect of fructose concentration on such network. Rhenium deposition with different fructose concentrations is studied on rotating disc electrodes. X-ray fluorescence, X-ray diffraction, and four point probe measurements at cryogenic temperature are used to study the deposition rate, crystallographic structure, and superconductivity of film, respectively.
