Conclusions

  1. 1.

    Criteria have been formulated for the suitability of modified electrodes in systems for the photoseparation of charges.

  2. 2.

    By means of cyclic current-voltage curves, a study has been made of the characteristics of modified electrodes coated with films of polyxylideneviologen-polysulfostyrene and with liquid films of octadecylviologen-decanol. It has been shown that the mechanical method of depositing polymer films, if the required coverage of the electrode is obtained, gives films that are too thick, characterized by a “charge diffusion” time that is 3–4 orders of magnitude greater than that required for use of the modified electrode in separating charges in systems for the photodecomposition of water.

  3. 3.

    A route has been mapped out for the improvement of modified electrodes for use in photoelectrochemical cells for the decomposition of water.
