چکیده

Rarely-observed polycrystalline twinned Pt nanoparticles (NPs) and length-controlled Pt nanorods (NRs) with exposed high index facets were prepared through an unexpectedly catalytic growth approach from low-cost Mn(3)O(4) NPs. The as-prepared Pt NRs exhibit higher catalytic activity and better stability for the oxidization of methanol than commercial Pt/C catalysts, indicating the promise of this catalyst in direct methanol fuel cells.

The mechanisms of platinum-catalyzed silicon nanowire growth

Platinum (Pt) has beenknown as a catalyst material for vapor-liquid-solid (VLS) synthesis since the mid 1960s with the potential to grow electronic grade silicon nanowires (SiNWs). In contrast to gold-based growth, Pt-catalyzed SiNW synthesis has rarely been studied, most likely due to higher synthesis temperatures and the formation of multiple Pt silicide phases. Here we present the growth of...

Selective growth of metal and binary metal tips on CdS nanorods.

Advances in the size1 and shape2 control of solution-grown nanocrystals have driven recent interest in the development of welldefined multicomponent nanostructures. Composition control, through the incorporation of two or more distinct nanostructured components, represents an effective approach to tailoring the chemical and physical properties of nanocrystals. The resulting hybrid structures of...

Engineering single crystalline Mn3O4 nano-octahedra with exposed highly active {011} facets for high performance lithium ion batteries.

Well shaped single crystalline Mn3O4 nano-octahedra with exposed highly active {011} facets at different particle sizes have been synthesized and used as anode materials for lithium ion batteries. The electrochemical results show that the smallest sized Mn3O4 nano-octahedra show the best cycling performance with a high initial charge capacity of 907 mA h g(-1) and a 50th charge capacity of 500 ...

Effects of zeolite particle size and internal grain boundaries on Pt/Beta catalyzed isomerization of n-pentane

The impact of particle size and internal grain boundaries of Beta zeolites was investigated in n-pentane isomerization over bifunctional Pt/Beta catalysts, by comparing the catalytic performance of four assynthesized Pt/Beta samples that possess an identical Pt loading (0.5 wt%), but use four distinct Beta zeolites. Three of them contain polycrystalline zeolites, consisting of nano-sized crysta...

Explicit Detection of the Mechanism of Platinum Nanoparticle Shape Control by Polyvinylpyrrolidone

The irreversible adsorption of polyvinylpyrrolidone (PVP) on a series of well-defined platinum single crystal electrode surfaces has been investigated using voltammetry, ex situ XPS and DFT calculations. It is found that the adsorption of PVP is highly structure sensitive with strong adsorption exhibited by step and {100} terrace sites with only weak interactions observed between PVP and Pt{111...
