Electrochemical Characterization Of Metal Complexes In Molecular Sieves

Molecular sieves immobilized metal complexes have gained great interest and become a hot spot in the field of catalytic materials due to its moderate reaction condition, high catalytic activity and selectivity, ease separation, recovery, shape selectivity and unique site isolation. At present time, the researches in the field are mainly concentrated on their preparation, characterization and catalytic properties, among of which the research of the electrochemical properties of different metal complexes encapsulated in different zeolite is very important, which offer many important redox informations. As for a series of metal complexes/zeolite composite materials, to confirm the encapsulation, several ways were taken such as XRD, FTIR to prove it. Then, we made them into zeolite modified electrodes. Itwas made sure of the experiment conditions by Cyclic Voltammetry. As for the electrochemical properties, the Cyclic Voltammetric method was selected. It showed that:1. Pure metal complexes' electrochemistry activity was not much affected by the encapsulation, but the redox potential changed, which attribute to the structure and frame of molecular sieves.2. The structure of metal complexes twisted, which attribute to the frame of molecular sieves.3. As for single centre metal complexes, composite materials' electrochemistry activity become stronger with the stronger of the attracting electron ability of the substituent.
