Abstract

Monodispersed Pt nanoparticles protected with poly(N-vinyl-2-pyrrolidon) were synthesized from H₂PtCl₆ by the methanol reduction. The structure of obtained nanoparticles was shown to be analogous to that in bulk crystals, and the particle size was determined to be 3.2 ±0.7 nm from the observation of TEM images. Hydrogen adsorption into particles was investigated by observing PCT curves repeatedly measured at 303 K. From the result of PCT measurements, the amount of absorbed hydrogen in the present size-controlled nanoparticles was found to be more than that in Pt black.
