摘要：

A platinum (II)-doped graphitic carbon nitride (Pt2+@g-C3N4) nanozyme was prepared in this work. Compared to g-C3N4, Pt2+@g-C3N4 shows enhanced peroxidase-like activity. According to DFT calculations and ESR measurements, the Pt on the surface of g-C3N4 accelerates the decomposition of H2O2 into center dot OH and consequently accelerates TMB oxidation. Furthermore, as a proof of concept, the obtained Pt2+ 2.30@g-C3N4 was applied in the detection of glucose with an LOD of 0.01 mM. The reproducibility and precision tests of the glucose detection method based on Pt-2.30(2+)@g-C3N4 show that this ...
