Poly(acrylic acid) (PAA) surface-modified gold nanorods, contained in deionized ultra filtered (DIUF) water, served as templates for the formation of gold (Au), palladium (Pd), and platinum (Pt) nanoparticles upon reduction with NaBH4. This provided nanoparticles with respective diameters of 7.0 ± 0.7, 4.1 ± 0.4, and 5.1 ± 0.5 nm. Varying amounts of Pt metal salt were used in EG, which acts as both a solvent and a reducing agent, ranging from 0.1, 0.2, and 1.0 mg/mL, to provide control over nanoparticle diameters of 2.0 ± 0.5 nm, to 4.0 ± 0.5 nm, and 6.2 ± 1.9 nm, respectively. Nanoparticle diameter was also controlled in DIUF water by varying the amount of Pt metal salt from 0.1, 0.2, and 1.0 mg/mL, producing Pt particle diameters, respectively, increasing from 2.7 ± 0.3 nm to 4.1 ± 0.5 nm, and 6.0 ± 0.6 nm.
