“…[7][8][9] Recently, various Pt nanoparticle shapes have been successfully synthesized, such as Pt nanocubes (Pt NCs), [4,6,10,11] nanorods, [12] nanotubes, [13] and dendritic nanoparticles. [3,14,15] Among all these morphology-controlled Pt nanoparticles, NCs are particularly interesting because of their special catalytic activity in different catalytic reactions. For example, Pt NCs with (100) surfaces are more active and selective than conventional NO catalysts.…”

A novel and very effective wet chemical route for the preparation of metal dendritic nanostructures was developed by starting from VOSO 4 and Ag 2 SO 4 (or K 2 PdCl 4 ) in aqueous solution at room temperature. No template or surfactant was used. VOSO 4 serves as the reducing agent for the silver salt, and the resulting silver nanoparticles and nanocrystallites are then arranged into dendritic structures. The morphologies of the dendrites are found to be heavily influenced both by the molar ratio and the concentrations of the reac-

Perfect platinum (Pt) nanocubes with high density have been synthesized by controlled reduction of hexachloroplatinic acid in the presence of H 2 SO 4 and HCl, employing a pair of low-resistivity fastened silicon (FS) wafers at room temperature. The presence of the additive charges (induced by prior etching of the silicon surface with HF to remove any SiO 2 layer) between the interfaces of the FS surface results in a high charge density and facilitates fast deposition of Pt nanoparticles via electroless plating. The charge density, stirring time, and homogeneity of the aqueous solution influenced the geometrical shapes of the Pt nanoparticles. The parameters were finely tuned in order to control the nucleation and growth rates and obtain perfect Pt nanocubes. The perfect Pt nanocubes were single crystalline with exposed {100} facets. Per equivalent Pt surface areas, the perfect Pt nanocubes showed enhanced catalytic activity relative to truncated Pt nanocubes or spherical Pt nanoparticles for the electrooxidation of liquid feed fuels such as methanol and ethanol. Moreover, there a strong correlation was observed between the optical, electrical, thermal, magnetic, and catalytic properties of the perfect Pt nanocubes which should lead to a variety of technological applications of these materials.
