Fig. 1From: Plasmonic Pd Nanoparticle- and Plasmonic Pd Nanorod-Decorated BiVO4 Electrodes with Enhanced Photoelectrochemical Water Splitting Efficiency Across Visible-NIR Region a XRD pattern of the BiVO4 film. The vertical lines indicate JCPDS diffraction peaks of FTO (blue) and monoclinic BiVO4 (red) and b UV-vis absorption spectrum of the BiVO4 film.
