电催化剂Pt-WO_3用作葡萄糖传感器工作电极性能的研究

The Study of A New Electrocatalyst Pt - WO_3 as the Work Electrode of Glucose Sensor

用铂金属和溶解的三氧化钨电化学共沉积制备P_1/WO_3电极,利用流动分析等方法研究厂电极作为葡萄糖传感器工作电极的性能.结果表明:该电极具有工作电位低、催化活性高、响应快、重复性好、抗干扰能力强及使用寿命长等特点.在2×10^(-3)～4×1O^(-2)mol/L范围内.

A new Pt/WO3 electrode fabricated by Pt and WO3 co - deposition was described. Its electrocatalytic performance as glucose sensor was investigated by flow detection .The developed electrode has low working potential, high catalytic activity , rapid response , high responsibility , less interference and long lifetime.The peak current of sensor response to glucose is linear in concentration range from 2 × 10-1-4× 10-2mol/L.
