What are the characteristics of the silver nanoparticles synthesized using glycerol?

One study developed a straightforward polyol method for synthesizing spherical silver nanoparticles (AgNPs), with a median size of 12.2 nm in glycerol at a low temperature (60 °C). The XRD analysis revealed the highly crystalline structure of bulk Ag(0) in the solid state. Characteristic diffraction peaks were observed at 20 values of 38.3°, 44.5°, 64.6°, and 77.5° attributed to face-centered cubic crystal planes of (111), (200), (220), (311). HR-TEM micrographs confirmed the spherical shape with a mean particle size of 12.2 nm. The d-spacing values for the (111) and (200) planes were estimated to be 0.238 nm and 0.196 nm, respectively, indicating good crystallinity. The exclusive formation of zero-valent AgNPs in glycerol was declared, showing a spherical shape and a small nano-size (less than 20 nm).

The silver nanoparticles (AgNPs) synthesized in glycerol are spherical with a median particle size of 12.2 nm. They possess a highly crystalline face-centered cubic structure, as confirmed by XRD analysis and HR-TEM micrographs.
