Fig. 1. (a) XRD patterns of monoclinic scheelite BiVO4 (JCPDS 14-0688) and BiVO4-140/160/180. The diffraction peaks at 2θ values of 18.67°, 18.99°, 28.95°, 30.55°, 34.50°, 35.22°, 39.78°, 42.46°, 45.59°, 46.71°, 50.31°, 53.31°, 58.53°, and 59.26° are indexed to the (110), (011), (121), (040), (200), (002), (211), (051), (231), (240), (202), (161), (321), and (123) crystal planes of monoclinic BiVO4. (b) UV/Vis absorption spectra of BiVO4-140/160/180 and corresponding Tauc plots (insets). The lowest bandgap (2.4 eV) was calculated from each UV/Vis absorbance spectrum. (c) Transient photocurrents of BiVO4-140/160/180. (d) PL spectra of BiVO4-140/160/180 (λex = 320 nm). (e) Size distributions of BiVO4-140/160/180 and commercial BiVO4 determined by DLS using BiVO4 dispersed in 2-MeTHF (0.025 mol/L). (f?i). SEM images of BiVO4-140/160/180 and commercial BiVO4.
