摘要：

Here, we report a new method for constructing single-atom platinum/CNC (SA-Pt/CNC) nanozyme using the impregnation adsorption method with porous carbon nanocages (CNC) as the carrier. The microstructure of SA-Pt/CNC was thoroughly analyzed using transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), and X-ray photoelectron spectroscopy (XPS). Enzyme activity tests showed that SA-Pt/CNC exhibited excellent peroxidase-like activity, efficiently catalyzing the oxidation of various substrate molecules by hydrogen peroxide.
