Fig. 7From: Plasmonic Pd Nanoparticle- and Plasmonic Pd Nanorod-Decorated BiVO4 Electrodes with Enhanced Photoelectrochemical Water Splitting Efficiency Across Visible-NIR RegionSpatial distribution of electric-field for a NP-BiVO4 and b NR-BiVO4 with excitation wavelengths of 500 and 900 nm, respectively. The incident light is along a specific direction (z axis). c Schematic illustration of the plasmon-induced charge carrier transfer under visible or NIR light illumination at Pd/BiVO4 interfaceBack to article page
