摘要：

This study describes the fabrication of a sensitive modified electrode for detecting hydrogen peroxide. The glassy carbon surface was modified with a composite containing CeO2 quantum dots and carbon sheets. The ultra-small grain size of nanoparticle endows the electrode with excellent electrocatalytic activity. As a result, the electrode shows electrocatalytic reduction activity toward H2O2 at a potential of -0.5 V. The CeO2 quantum dots sensor shows a satisfactory performance for detecting hydrogen peroxide with a linear range of 2 ppm-1000 ppm, and a limit of detection (LOD) of 900 ppb. These findings show that CeO2 quantum dots have a great potential for applications in electrochemical sensing.
