Abstract

The effects of magnetic processing on the morphological, electrochemical, and photoelectrochemical properties of electrodes modified with nanoclusters of a C60 derivative with a positive charge (C60N+) and methylphenothiazine (MePH) were examined in the absence and presence of magnetic processing using three different magnetic environments induced using a strong magnetic field. The atomic force microscopy (AFM) results indicate that the C60N+-MePH nanoclusters in the presence of magnetic processing was smaller than that in the absence of magnetic processing. The first reduction peaks corresponding to the C60N+ nanocluster in the presence of magnetic processing were negative-shifted compared with those in the absence of magnetic processing. The potential dependences of the photocurrents of the electrodes modified with C 60N+-MePH nanoclusters in the presence of magnetic processing were also different from those in the absence of magnetic processing. The magnetic field effects during AFM, and differences in electrochemical and photoelectrochemical measurements can most likely be ascribed to the difference in the reduction potentials between the absence and the presence of magnetic processing due to the morphological change of C60N+ nanoclusters.
