Figure 4From: New one-pot synthesis of Au and Ag nanoparticles using green rust reactive particle as a micro-reactorIn-lens SEM microscopy pictures. Solid samples obtained after reaction between (a) GRc and AuIII, R = 200% and (b) GRc and AgI, R = 120%. Size distribution histograms are given in the inserts (a) 1 μm2, 38 Au nanoparticles and (b) 1 μm2, 26 Ag nanoparticles.Back to article page
