Fig. 5From: ZnO Porous Nanosheets with Partial Surface Modification for Enhanced Charges Separation and High Photocatalytic Activity Under Solar IrradiationUV-vis DRS of ZnO, BiVO4, and BiVO4-modifying ZnO with different Bi/Zn molar ratios. It shows that the harvest of visible light for BiVO4-modifying ZnO nanosheets enhances with the increasing Bi/Zn ratioBack to article page
