Beschreibung
Zusammenfassung:	A nanozyme material and a preparation method thereof are provided. In the preparation method, Prussian blue (PB) is used to regulate the peroxidase activity of Fe,NA/CDs, and then gold nanoparticles are synthesized with Fe,NA/CDs as a reducing agent and a stabilizing agent. The nanozyme material has both a peroxidase activity and a Raman enhancement effect, which can be used for nanozyme-based surface-enhanced Raman spectroscopy (SERS). An embodiment of the present disclosure also provides a method for rapidly detection of a Pb2+ ion, which is based on a color change or an additional Raman SERS signal generation caused by nanozyme oxidation. Such sensing signals (colorimetric and SERS analysis) are derived from a catalytic oxidation reaction of ABTS or TMB, while the presence of Pb2+ specifically inhibits the oxidation, such that the rapid detection of Pb2+ can be achieved.
