Abstract
The photoelectrochemical properties of the ferrites ZnFe2O4, MgFe2O4 and Li0.5O4 with the spinel structure are reported. The ferrites seem reasonable candidates for photoanodes in a photoelectrochemical cell, because of their 2.2 eV bandgap. The results show, however, that the visible absorptivity, the flat-band potential and the recombination processes limit severely
