Figure 8From: Size-controlled synthesis of monodispersed gold nanoparticles via carbon monoxide gas reduction TEM images of AuNPs synthesized by CO reduction of HAuCl 4 . A, B, C, and D are TEM images of AuNPs synthesized without the addition of K2CO3. E and F are AuNPs synthesized from a hydrolyzed solution of aqueous HAuCl4 via the addition of K2CO3. The corresponding sizes of the AuNPs are 4, 6, 15, 25, 50, and ~100 nm respectively.Back to article page
