摘要: A method for size-controlled synthesis of chemically clean silver nanoparticles is proposed and described. The based on the reduction silver(I) oxide by hydrogen gas in water offers advantages being easily scalable able to produce essentially naked particles still exhibiting long-term stability with metal surface readily accessible various chemical modifications. allows any diameter between 15 200 nm simply varying reaction time. addition filtration centrifugation techniques produces suspensions narrow size distribution relatively high, 1012−1014 particles/mL, concentration. complexating agents potentially control nanoparticle shape. were characterized UV−vis spectroscopy, electron microscopy, X-ray diffraction techniques.
