Unearthing Atomic Dynamics in Nanocatalysts

ACS Applied Materials & Interfaces
Being able to access the rich atomic-scale phenomenology, which occurs during the reactions pathways, is a pressing need toward the pursued knowledge-based design of more efficient nanocatalysts, precisely tailored atom by atom for each reaction. However, to reach this goal of achieving maximum optimization, it is mandatory, first, to address how ...

Nanocatalysts for Ethanol Oxidation. Synthesis and Characterisation

Portugaliae Electrochimica Acta, 2009
Carbon-supported binary PtSn/C and ternary PtSnNi/C catalysts were prepared for the electro-oxidation of ethanol. The carbon-supported nanoparticles were synthesised by employing a modified polyol methodology and characterised in terms of structure, morphology and composition by using XRD, EDX and TEM techniques.
