Electrochemical Characterization And Catalysis Properties Of Metal Complexes In Molecuiar Sieves

By different means, several kinds of metal complexes were encapulated in the supercages of NaY zeolite. To confirm the encapsulation, several ways were taken such as XRD , FTIR and DRS to prove it. Zeolite-modified microelectrodes were then prepared . It was made sure of the optimum of preparation of electrodes and experiment conditions. As for the characterization, the Cyclic Voltammetric method was selected. It showed that pure metal-complexes' electrochemistry activity was not much affected by the encapsulation. The influence of zeolite structure on the metal-complexes was studied, which reflected on the peak potentials and their quantities. In this paper were studied the catalysis activity and showed the effect about different complexes, different metals and metal contents, etc. Combined with the result of cyclic voltammetric method, it also indicatd that all kinds of factors such as the structure change or site of the metal-complexes in the zeolites had different results. The experiment proved that cyclic voltammetry could be used as an efficient method to study metal-complexes Ln the zeolite.
