Controlling and self assembling of monodisperse platinum nanocubes as efficient methanol oxidation electrocatalysts.
An efficient synthetic approach that enables not only the control of Pt nanocubes but also the one-pot fabrication of novel Pt nanocube assemblies was developed for the first time. The integration of well-defined building blocks and unique superstructures endows Pt nanocube assemblies with enhanced performance in the methanol electrooxidation, showing a new concept for further enhancing the per...
متن کاملCarbon monoxide-controlled synthesis of surface-clean Pt nanocubes with high electrocatalytic activity.
A new strategy for synthesis of Pt nanocubes on various supports by reduction of a Pt precursor under a CO atmosphere was described. The as-prepared Pt nanocubes supported on multi-walled carbon nanotubes exhibited high activity toward methanol electrooxidation.
متن کاملMonodispersed platinum nanocubes for enhanced electrocatalytic properties in alcohol electrooxidation.
We report Pt nanocubes of ∼4.5 nm in size synthesized by thermal decomposition in the presence of PVP. The Pt cubic electrocatalysts with dominantly exposed {100} facets show much improved electrocatalytic activities in methanol, ethanol and formic acid electrooxidation.
متن کاملSynthesis and characterization of Pt3Co bimetallic nanoparticles supported on MWCNT as an electrocatalyst for methanol oxidation
The impregnation method was used to synthesize Pt and Pt3Co supported on MWCNTs applying NaBH4 as the reducing agent. The structure, morphology, and chemical composition of the electrocatalysts were characterized through SEM, XRD, and EDX. X-ray diffraction showed a good crystallinity of the supported Pt nanoparticles on the composites and showed the formation of Pt3<...
