通过简单且环保的策略，原位构建了高度分散的二维纳米结构超薄黑磷纳米片（BPN）-集成金纳米颗粒（AuNP）杂化物。在这种绿色便捷的合成过程中没有引入额外的还原剂、表面活性剂或聚合物模板。所得的 AuNPs/BPNs 纳米杂化物通过紫外可见分光光度计、拉曼光谱、透射电子显微镜 (TEM)、X 射线光电子能谱 (XPS) 和电感耦合等离子体原子发射光谱 (ICP-AES) 进行表征。 BPNs 的含量在调节 AuNPs/BPNs 杂化物的形态和化学状态方面起着至关重要的作用，对此已经进行了系统研究并进行了详细讨论。由于高密度超小型 AuNPs 得到了适当的稳定和调节，而不会被周围的超薄 BPNs 钝化，因此所得的 AuNPs/BPNs 杂化物表现出优异的催化/抗菌性能和长期稳定性，受益于 AuNPs 和 BPNs 结构之间可能的协同增强效应。这种简单、温和且环境友好的策略可以推广到其他金属或金属氧化物掺杂配合物的制备，并在潜在的催化、生物分析和生物医学应用中具有广阔的前景。
Highly dispersed 2D-nanostructured ultrathin black phosphorus nanosheets (BPNs)-integrated Au nanoparticles (AuNPs) hybrids were constructed in situ through a facile and environmentally friendly strategy. No additional reductants, surfactants, or polymer templates were introduced during this green and convenient synthesis process. The resulting AuNPs/BPNs nanohybrids were characterized by UV-vis, Raman spectroscopy, transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and inductively coupled plasma-atomic emission spectroscopy (ICP-AES). The content of BPNs plays an essential role in modulating the morphologies and chemical states of AuNPs/BPNs hybrids, which have been investigated systematically and are discussed in detail. As high-density ultrasmall AuNPs are properly stabilized and accommodated without passivation by the 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. This simple, mild and environmentally benign strategy could be generalized to the preparation of other metal- or metal oxide-doped complexes and holds great promise for potential catalytic, bio-analytical and biomedical applications.
