In this paper, the chemical reduction method was used to prepare silver nanoparticles with different morphologies and sizes by controlling the proportion of ascorbic acid and silver nitrate at room temperature. In the experiment, the molar ratio of ascorbic acid and silver nitrate was mainly 1:1, 1:2, 1:4, 1:8, 2:1, 4:1 and 8:1 to prepare nano silver. The morphology of silver nanoparticles was observed by scanning electron microscopy (SEM) and the phase content was determined by X-ray diffraction (XRD). The results show that the obtained material is pure silver nanoparticles, and the silver nanoparticles are spherical and multilevel branched.
