Fig. 10. (a) The current–voltage behavior of the AACVD grown BiOBr film under 100 mW cm–2 illumination in 0.5 M Na2SO4 electrolyte. A photocurrent of ca. 0.38 mA cm–2 at 1 V vs. Ag/AgCl was observed. (b) The stability of the BiOBr film at an applied voltage of 1.0 V vs. Ag/AgCl. There was a 23% decrease after 1 hour.
