Abstract
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 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.
