Black phosphorus: a two-dimensional reductant for in situ nanofabrication

Abstract

The reducing capability of two-dimensional black phosphorus is demonstrated. The high reducing ability and unique two-dimensional morphology of black phosphorus not only facilitate in situ synthesis of Au nanoparticles and BP@Au composites, but also enable multiscale control of local reduction of GO to reduced GO (rGO). The novel two-dimensional reductant has large potential in various in situ nanofabrication applications.
