Development of functional black phosphorus nanosheets with remarkable catalytic and antibacterial performance

Abstract

Highly-dispersed 2D-nanostructured ultrathin black phosphorous nanosheets (BPNs)-integrated Au nanoparticles (AuNPs) hybrids are constructed in situ through a facile and environmental-friendly strategy. No additional reductants, surfactants, or polymer templates are introduced during this green and convenient synthesis process. The resulting AuNPs/BPNs nanohybrids were characterized by using UV-vis, Raman spectroscopy, transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and inductively coupled plasma-atomic emission spectrometry (ICP-AES). The content of BPNs plays an essential role for modulating the morphologies and chemical states of AuNPs/BPNs hybrids, which are investigated systematically and discussed in detail. As high-density ultrasmall AuNPs are properly stabilized and accommodated without passivation by surrounding ultrathin BPNs, the resulting AuNPs/BPNs hybrids exhibit excellent catalytic/antibacterial properties and long-term stabilities benefiting from a possible synergistic enhancement effect between AuNPs and BPNs constructs. The simple, mild and environmental-benign strategy could be generalized to the preparation of other metal- or metal oxides-doped complexes which hold great promise for potential catalytic, bioanalytical and biomedical applications.
