摘　　要：氧化钛纳米带是一种性能优异的新型功能材料,其合成方法及应用是研究的热点。采用乙醇热溶剂法合成了氧化钛纳米带,并通过扫描电镜观察了纳米带的形貌。将氧化钛纳米带固定到电极表面,采用恒电位沉积钯纳米粒子后制得吗啡电化学传感器。结果表明,该传感器稳定性好、灵敏度高、选择性好、制作简单、成本低,应用于血清中吗啡的测定,结果令人满意。Titanium dioxide nanobelts are a new type of high performance functional materials, while synthesis method is the research hot spot. Ethanol thermal solvent was used to synthesize titanium dioxide nanobelts. Scanning electron microscopy was used to characterize the morphology of the nanobelts. Pd nanoparticles were eleetrodeposited on the glassy carbon electrode modified with obtained titanium dioxide nanobelts/chitosan film to construct morphine electrochemical sensor. The experimental results show that the sensor has good stability, high sensitivity and selecti- vity, simple preparation procedure and low cost. The sensor is applied to determine morphology with satisfactory.
