Abstract: Water-dispersed silver nanoparticles (AgNPs) were quickly synthesized with glucose (C6H12O6) as reducing agent and polyvinyl pyrrolidone (PVP) as surfactant at room temperature by liquid reduction method, and characterized. The results show that the spherical-shaped and phase-pure crystalline nano AgNPs with the diameters of 30~55 nm can be obtained by adjusting the concentrations of NaOH solution and PVP. And the colloidal silver nanoparticles exhibit an activity in the reduction of hydrogen peroxide (H2O2). The change in the absorbance strength of surface plasmon resonance is linear with the concentration of H2O2. Good sensitivity and linear response over the wide concentration range of 5.0′10-7~5.0′10-2 mol/L H2O2 are established.

摘要： 以葡萄糖(C6H12O6)为还原剂、聚乙烯吡咯烷酮(PVP)为分散剂，采用液相还原法在室温水体系中快速制备不同浓度的纳米银粒子，对产物进行了表征，并将其用于H2O2检测. 结果表明，通过控制NaOH和PVP用量，可制得粒径30~55 nm、纯相的球形纳米银胶体，在H2O2检测中活性良好. 纳米银胶体表面等离子共振峰强度变化与H2O2浓度呈线性关系，H2O2的检测灵敏度高，检测限为5.0′10-7~5.0′10-2 mol/L.
