摘　　要：Design and synthesis of super-nanostructures have obtained increasing attention in nanotechnology.A series of superstructured-nanonetwork and nested-nanonetwork bismuth compounds have been developed recently based on lattice-directed topotactic transformation.Here we further develop some specific superstructures by transformation within different crystalline types,such as hexagonal BiI3micro/nanoplates,tetragonal BiOI micro/nanoplates and nested two-dimensional(2D)orthogonal Bi2S3nanonetworks,based on the lattice matching between the product and precursor.The method offers a convenient and common route in synthesizing heterojunctions and bimaterial nanostructures similarly.Design and synthesis of super-nanostructures have obtained increasing attention in nanotechnology. A series of superstructured-nanonetwork and nested-nano- network bismuth compounds have been developed recently based on lattice-directed topotactic transformation. Here we further develop some specific superstructures by transformation within different crystalline types, such as hexagonal BiI3 micro/nanoplates, tetragonal BiOI micro/ nanoplates and nested two-dimensional （2D） orthogonal Bi2S3 nanonetworks, based on the lattice matching between the product and precursor. The method offers a convenient and common route in synthesizing heterojunctions and bi-material nanostructures similarly.
