Figure 1

Generation of AgNPs: (A) UV–Vis absorption spectrum of silver nanoparticles (AgNPs) with λ = 300–600 nm, the central peak is concentrated at 350–450 nm. The silver nanoparticle colloid color can be seen to be bright yellow; (B) Nanoparticle Size Analyzer (NSA) size analysis of silver nanoparticles (AgNPs). The AgNP particle size was measured mainly at 47 nm; (C) TEM image of silver nanoparticles (AgNPs) synthesized by silver nitrate, trisodium citrate, and sodium borohydride. TEM image of silver nanoparticles (AgNPs): silver nanoparticles were synthesized when sodium borohydride was added and stirring was stopped immediately (D), and after 60 min (E); and (F) TEM image of Ag amalgam crystals (AgHg).
