In this work, a simple and facile strategy was developed for the fabrication of large sized Au spherical architectures (AuSAs) with flexible nanoflakes as subunits by using a liquid-liquid interfacial reaction route at room temperature. The as-prepared AuSAs were characterized and analyzed by scanning electron microscopy, X-ray powder diffraction, thermogravimetric analysis and transmission electron microscopy. The effects of a series of factors on the morphologies and structures of the products were studied in detail. On the basis of control experiments and molecular dynamics simulations, a possible growth mechanism was suggested for the formation of AuSAs at the interface between toluene and water. Furthermore, due to the relatively large particle size, high surface roughness and high symmetry of the spherical characteristics, AuSAs could be used to perform individual particle SERS investigation, which demonstrated remarkable SERS responses and high reproducibility.

“…The catalytic reduction of aromatic nitrocompounds using noble metal NPs in the presence of NaBH 4 has been widely investigated for the efficient preparation of aromatic aminocompounds [35][36][37][38][39][40]. Therefore, the reduction of 4-NP-4-AP with an excess amount of NaBH 4 was used as a model system to evaluate the catalytic activity of the prepared nanocomposite catalysts.…”

Nanosheet of PdNiZn and nanosphere of PdNiZn/reduced‐graphene oxide (RGO) with sub‐3 nm spheres have been successfully synthesized through a facile oil‐water interfacial strategy. The morphology and composition of the films were determined by X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive analysis of X‐ray (EDAX) and elemental mapping. In the present study, we have developed a method to minimize the usage of precious Pd element. Due to the special structure and intermetallic synergies, the PdNiZn and PdNiZn/RGO nanoalloys exhibited enhanced catalytic activity and durability relative to Pd nanoparticles in Suzuki‐Miyaura C‐C cross‐coupling reaction. Compared to classical cross‐coupling reactions, this method has the advantages of a green solvent, short reaction times, low catalyst loading, high yields and reusability of the catalysts.
