Ferrocenyl surface species on platinum and conducting glass electrodes, and on photoelectrochemical n-silicon electrodes

Abstract

Cyclic voltammetry on platinum and conducting glass electrodes derivatised with a variety of ferrocenyl compounds has indicated, largely from the scan-rate dependence, peak separation, and coverage, that any particular derivatant might in successive experiments evince behaviour from near-irreversible to near-reversible, though most show the latter. These observations led to studies of the more viable derivatants on n-doped silicon under visible illumination, and considerable stabilisation of the silicon was shown by (dichloromethylsilyl)ferrocene. It was moderately successful also on GaAs.
