Electrochemical characterization of a novel salen-type modified electrode

Article Abstract:

The electrochemical properties of nickel(II) complexes with Schiff base ligands have been studied. Polymer films have been prepared by oxidatively electropolymerizing the nickel(II) complex on Pt electrodes in CH3CN/O.1 mol dm (super -3) tetraethylammonium perchlorate. Results indicate that films of poly(Ni(saltMe)) can be made to exhibit three types of charge transport modes by altering the film thickness and the experimental time scale. There is also a transition from semi-infinite diffusion to finite diffusion with time observing the potential step.

Oxygen mobility in CeO(sub)2 and Ce(sub0xZr(1-x)O(sub)2 compounds: study by CO transient oxidation and (sup)18O/(sup)16O isotopic exchange

Article Abstract:

Results demonstrate that Cerium-Zirconium mixed oxides exhibit high oxygen storage capacity with the highest oxygen exchange reactivity at 400 C. Data further indicate that unlike mixed oxides, cerium alone is not capable of exchanging large amounts of oxygen.
