Facile construction and peroxidase-like activity of single-atom platinum nanozyme
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 mol-ecules by hydrogen peroxide.
