ABSTRACT
Black phosphorus (BP) nanostructures have been identified as a highly feasible 2D-material with excellent electronic properties, tunable bandgap, and good in-plane anisotropy, illustrating their aptitude for the construction of heterostructures. The creation of a 3D architecture using 2D nanosheets as building blocks has been demonstrated to be a successful way of using the amazing properties of 2D materials. A large number of exposed active sites for ion absorption and reaction are provided by the 3D architecture by inhibiting the rearrangement of 2D nanosheets with a wide area to the volume ratio. Also, such a 3D architecture often provides pores or channels for the diffusion and transportation of ions. This chapter addresses recent development in the designs of BP-based heterostructures, as well as various applications such as electronic and optoelectronic devices, energy storage systems, photocatalysis and electrocatalysis and biological applications.
