Figure 2

(a) UV-Visible DRS spectra, (inset of a) plots of (ahv)2 versus the photon energy (hv), (b) the images of energy band structure of Bi4V2O11, (c) Transient photocurrent responses of Bi4V2O11 under a bias of 0.4V and 0.8 V and (d) EIS Nyquist plots the Bi4V2O11 electrode in the dark and under UV-Visible light irradiation. The reference electrode was Ag/AgCl, and the electrolyte was 0.2 M Na2SO4.
