摘要:
A simple, effective and interesting method for gold nanoparticles (AuNPs) synthesis with nonthermal microplasma is developed in this study. The device of dielectric barrier discharge (DBD) microplasma generator with a spray portion is designed and fabricated for uniform AuNPs synthesis. The AuNPs can be synthesized effectively in situ by the DBD microplasma generated on the nozzle of the pneumatic micro-nebulizer. The mechanism of the AuNPs formation under microplasma, the effect of nebulization for uniform AuNPs synthesis and other significant parameters are investigated in the experiment. The morphology and optical properties of the synthesized gold nanoparticles are also characterized. The minimum particle size in average obtained by the proposed method is 4.9 +/- 1.1 nm. The particle size of AuNPs can be controlled in the range of 4.9-16.8 nm by the various aqueous solution conditions.
