摘　　要：设计灵敏、快速响应的催化剂对于葡萄糖生物传感器具有重要意义。在本文中,我们用溶剂热法一步快捷的合成了两种不同相的铜铁硫属化合物CuFeS_(2)和Cu_(5)FeS_(4)。在加入导电碳黑VXC-72的条件下,发现CuFeS_(2)的灵敏度为212uAmM^(-1)cm^(-2),线性范围达3.63mM,另一种相Cu_(5)FeS_(4)的灵敏度可达到744 uAmM^(-1)cm^(-2),线性范围达4.13mM,具有作为良好葡萄糖传感器的潜力。It is of great significance to design sensitive and responsive catalysts for glucose biosensors.In this paper,two different phases of CuFeS_(2) and Cu_(5)FeS_(4) were synthesized by solvothermal method in one step.With the addition of conductive carbon black VXC-72,it is found that the sensitivity of CuFeS_(2) is 212uAmM^(-1)cm^(-2) with a linear range of 3.63mM,and the sensitivity of another phase Cu_(5)FeS_(4) is 744 uAmM^(-1)cm^(-2) with a linear range of 4.13mM.It has the potential as a good glucose sensor.
