Abstract :
A facile chemical strategy for the one-step synthesis of platinum nanoparticles
(Pt NPs) is demonstrated in this paper. Pt nanoparticles were prepared using chemical
reduction in NaBH4 and were capped in a polyvinyl alcohol (PVA) colloidal suspension. The
morphology and structure of as-synthesized Pt nanoparticles are characterized by UV–Vis
spectroscopy, X-ray diffraction (XRD) and transmission electron microscopy (TEM). The
results indicated that the Pt nanoparticles with a narrow size distribution (2–4 nm) were
highly crystalline in nature. In addition, the electrochemical properties and the
electrocatalytic activities of Pt nanoparticles modified glassy carbon electrode (GC) were
characterized by cyclic voltammetry (CV). The experiments yielded evidence that Pt
nanoparticles facilitated hydrogen peroxide reduction, and exhibited favorable electrooxidation
activity towards NADH and methanol, showing excellent catalytic activity, and
holding a good promise in catalytic and bioanalytical applications.
