The Synthesis of PtFe/C and Its Application in Non-Enzymatic Glucose Sensor

20 wt% PtFe/C catalysts were prepared by a chemical reduction method at high temperature. The catalysts were characterized by X-ray diffraction, transmission electron microscopy, and electrochemical testing. The sensor based on PtFe/C showed a detection limit of 0.03 mM and high sensitivity with linear range from 0.1 mM to 13.5 mM. The sensor still had high selection for glucose in the presence of commonly interfering species, such as ascorbic acid, acetamidophenol, and uric acid. The as-prepared glucose sensor has good anti-interference performance.
