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.

Strong Metal‐Support Interaction Driven Janus Reconstruction in PtRu Alloys for Low‐Temperature Hydrogen Storage

Advanced Science, EarlyView.
Strong metal‐support interactions (SMSI) drive the spontaneous segregation of RuPt alloy into Janus nanoparticles on CeO2, spatially partitioning Pt‐rich domains for H2 dissociation and Ru‐rich domains for toluene adsorption. This Janus nanocatalysts yield a turnover frequency of 10 906 h−1 for toluene hydrogenation at 50 °C, which is 6.7 times that of

Magnetic‐Field‐Tuned Spin‐Dependent D‐Band and Bifunctionality in L10‐FeCoPt for Enhanced Methanol Oxidation

Advanced Science, EarlyView.
The d‐band center and bifunctional mechanism jointly regulate the amounts of adsorbed OH* and CO*, thereby enhancing electrocatalytic performance, while the application of an external magnetic field further boosts this performance. ABSTRACT The spin‐dependent electronic structure of transition‐metal alloys plays a key role in tuning the magnetic‐field ...
