Oxidase-Like Catalytic Performance of Nano-MnO2 and Its Potential Application for Metal Ions Detection in Water

Figure 4

Concentration-dependent kinetic study of the oxidase-like activity of nano-MnO2 for a 3 min reaction. Reaction conditions: [Nano-MnO2] = 0.005–0.3 mg·mL−1, [2,6-DMP] = 1.0 mmol·L−1. Error bars represent the standard deviation (n = 3).
