Abstract

Chiral Au@Pt nanoparticles (NPs) with optically plasmonic and catalytic active surfaces were sustainably prepared to serve as label-free surface enhanced Raman scattering (SERS) platform to distinguish D- and L-enantiomers of alanine and tartaric acid. Surface morphologies were characterized by high-angle annular dark-field imaging-scanning transmission electron microscopy (HADDF-STEM) and selected area energy diffraction (SAED) patterns. The amounts of Pt on chiral Au NPs were estimated by the inductively coupled plasma-optical emission spectrometer (ICP-OES) and X-ray diffraction (XRD). The versatile applications including the environmental hazardous species monitoring and the fundamental enantiomeric differentiation are demonstrated for the novelty of prepared materials. Au@Pt NPs were used as a unique platform of H₂O₂ and Hg²⁺ concentrations using UV-Vis absorption and surface enhanced Raman scattering (SERS). The chiral Au@Pt NP platform may provide an efficient approach to achieve chiral nanocatalysis for numerous chemical reactions.
