英文摘要：
Web-like ZnO nanostructures have been successfully synthesized using the potassium nitrate route at various temperatures to simplify conventional preparation methods. The structures and morphologies of the as-prepared products were characterized by X-ray powder diffraction （XRD） and field-emission scanning electron microscopy （FE-SEM）. The results showed that the reaction temperature was an important parameter, and that there was a feedback effect between nano-structure and growth parameters, combined with in situ micro-calorimetry, the reaction rate constants of the three systems were found to have been： 2.43×10-6, 2.70×10-8 and 3.12×10-7s-1 respectively. Furthermore, based on the relationship governing the potential differences between nanoand bulk ZnO, thermodynamic functions of nano-ZnO such as standard molar entropy （Sm,ZnO（nano））, standard molar Gibbs free energy of formation （△rGm,ZnO（nano））, and standard molar enthalpy of formation （△rHm,ZnO（nano）） have been calculated by the electrochemical method.
