As a precious metal nanomaterial, nano-silver has become the most interested research subject in nanoscience today due to its wide application in many fields. The synthesis methods of nanosilver, such as photochemical method, ultrasonic assisted reduction method, electrochemical reduction method, template method, radiation reduction method and biochemistry method, are briefly introduced. Some of the studies on chemical reduction method and microemulsion method and nano-silver synthesis are mainly discussed progress. Spectral absorption is an important property of nanosilver. The characteristic spectrum of UV-Vis is an important method to study the formation of nanosilver and the growth of nanocrystals. Therefore, the spectral characteristics of nanosilver are reviewed in detail. Finally, their research trends are also discussed.
