Fig. 11. (a) The current–voltage behavior of the AACVD grown BiOI film under 100 mW cm–2 illumination in 0.5 M Na2SO4 electrolyte. A photocurrent of ca. 0.15 mA cm–2 at 1 V vs. Ag/AgCl was observed. (b) The stability of the BiOBr film at an applied voltage of 0.5 V vs. Ag/AgCl. There was rapid decay after just 100 seconds.
