Fig. 1From: Steering Charge Kinetics of Tin Niobate Photocatalysts: Key Roles of Phase Structure and Electronic StructureX-ray diffraction patterns of tin niobate prepared in different pH value of the reaction solution (1~ 11) (a). Vertical bars below the patterns represent the standard diffraction data from JCPDS files for SnNb2O6 (01-084-1810) and Sn2Nb2O7 (00-023-0593).
