摘　　要：Nano-emulsion,a kinetically stable system of nanosized oil droplets in water has been numerously used as a medium for biological and medicinal processes.It is also used as a solubilizing medium for compounds or molecules that are insoluble or poorly soluble in aqueous medium in addition to its use as a penetration enhancer in dermatological processes.Ferrocene,a metallocene that is known to be quite insoluble in aqueous medium is liberally soluble in the prepared oil-in-water nano-emulsion.In this medium,ferrocene undergoes a quasi-reversible reaction process and its relevant electrochemical kinetic parameters such as the heterogeneous rate constant,ko,the formal redox potential,Eo,the half-wave potential,E1/2,the electron transfer coefficient,α,and its diffusion coefficient,D,are determined in this medium.These important electrochemical parameters including the observed current function have been used to formulate a plausible mechanism for the oxidation of ferrocene in the formulated nano-emulsion.
