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-nanonetwork bismuth compounds have been achieved recently based on lattice-directed topotactic transformation. Here we further develop some specific superstructures by transformation within different crystalline types, such as hexagonal BiI 3 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 bimaterial nanostructures similarly.
