Electrochemical properties of MC60 (M=Pd, Pt) covered electrodes
AltmetricsView Usage Statistics
The formation of electroactive films contg. fullerene and Pd or Pt was obsd. for solns. with the C60 and different metal complexes, Pd(PhCN)2Cl2, [Pd(CH3CO2)2]3, Pd(CH3CO2)2, [Pt(.mu.-Cl)Cl(C2H4)]2, cis-PtCl2(py)2, trans-PtCl2(py)2, and PtI2(py)2. Characterization of the film compns. by IR spectroscopy, MS and XPS shows that the films contain solely C60 and metal, as well as cations of the supporting electrolyte of the growth soln., that get incorporated during the cathodic growth process. Scanning electron micrographs of the films show that these consist mainly of spheres of .apprx.100 nm diam. and that the film thickness can be controlled by the no. of cycles used during the growth process. The films show cond. in the potential range of growth and this cond. is both electronic and ionic and have thus potential application in high-d. energy storage devices.
