|Title:||Organized media as redox catalysts on the reaction rate of Co<sup>III</sup>-Fe<sup>II</sup> redox couple|
Cobalt-Iron redox reaction
|Abstract:||Micelles catalyze the [Co(NH3)5Cl](NO3)2 - Mohr’s salt redox reaction due to the binding of the substrates onto the micellar surface by non-coulombic and coulombic interactions. This binding increases the encounter probability, leading to a substantially accelerated reaction. The kinetic studies of the same redox reaction have also been carried out in the water pools of non-ionic reverse micelles of Triton X-100/1-butanol in n-heptane. The findings indicate that probably substrate solubilization sites in micelles and reverse micelles are the interfacial and Stern regions. The reaction rates decrease with the water-to-surfactant mole ratio. The correct selection of surfactant for micelle, size of reverse micellar water pool cavity, different additives and the catalyst connecting nanoparticles control the electron transfer reaction rate in solution. Copper-sol induced catalysis occurs due to the availability of a suitable surface which acts as a mediator for the electron-transfer reaction between [Co(NH3)5Cl](NO3)2 and Mohr’s salt.|
