In this paper, a simultaneous synthesis and assembly strategy was investigated to synthesis the multiple-Pt-nanoclustes-C-shell nanostructures. The multiple-Pt-nanoclustes-C-shell nanostructures were hydrothermally achieved using glucose and platinum 2,4-pentanedionate as reactants, and the average particle size of Pt nanocluster was in the range of 2–3nm. Here glucose was used as the reducing agent to react with Pt 2+, and it also served as the source of carbonaceous shells. Transmission electron microscopy, scanning electron microscopy, and X-ray diffraction and UV-vis extinction spectra were used to characterize the core/shell nanostructures. The multiple-Pt-nanoclustes-C-shell nanostructures exhibit an excellent catalytic activity for the reduction of p-nitrophenol due to their small size, high dispersion, and high number density of the Pt nanoclusters in the C shell. |
