摘要:
利用螯合作用，将银纳米粒子担载于碳纳米管表面，并用透射电镜、EDX、X射线衍射和电化学测试对该纳米杂化材料进行了表征.研究显示，碳纳米管表面的银纳米粒子颗粒小、粒径分布窄；该纳米杂化材料对过氧化氢有较强的催化作用，当过氧化氢浓度在50 μmol/L~5 mmol/L范围内，浓度与还原峰电流呈线性关系，显示出该纳米杂化材料在过氧化氢检测方面具有潜在的应用前景.
Abstract:
Silver nanoparticles were loaded on the surface of carbon nanotubes via chelating method. The obtained nanohybrid structures were characterized by TEM, EDX, XRD and electrochemical technique. The results show narrow particle distribution of Ag nanoparticles was in the range of 1 to 5 nm. The nanohybrid has strong electrocatalytic effect on H2O2. When H2O2 ranges from 50 μmol·L-1 to 5 mmol·L-1, there is a good linearity relationship between H2O2 concentration and reductive peak current, which suggests the nanohybrid has the potential application in the determination of H2O2.?
