摘　　要：本文通过将Ti_(3)C_(2)与聚苯乙炔铜相结合,并通过在电极表面修饰葡萄糖氧化酶以进行别葡萄糖的特异性识别,成功构建了具有良好光电响应的光阴极葡萄糖传感器。该方法中,Ti_(3)C_(2)作为空穴传输的介质,有效促进聚苯乙炔铜的光生电子空穴对的分离,以此提高了光电响应数值,同时,聚苯乙炔铜本身具有p型半导体的优点,将其作为光阴极材料可以有效减少还原性物质的干扰。制备的光电化学传感器,在浓度范围为0.5mM至5.0 mM的葡萄糖溶液中具有良好的线性关系,检测限为0.018 mM。In this work,a photocathode glucose sensor with a favorable photoelectric response was successfully fabricated.This was accomplished by integrating Ti?C?with polymer phenylethnylcopper(PPhECu).Subsequently,the electrode surface was further modified with glucose oxidase for the specific identification of glucose.In this method,Ti?C?was used as a medium for hole transport.It effectively promoted the separation of photogenerated electron-hole pairs of PPhECu,thus improving the photoelectric response value.Meanwhile,PPhECu itself had the advantage of being a p-type semiconductor,which effectively reduced the interference from reducing substances.A good linearity was observed in glucose solutions ranging from 0.5 mM to 5.0 mM,with a detection limit of 0.018 mM.
