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.
