Area of Science:

  • Nanocatalysis
  • Surface Science
  • Computational Chemistry

Background:

  • Nanoparticle reshaping under reaction conditions is known, but the atomic-scale dynamics remain poorly understood.
  • Metastable structures formed during nanocatalyst transformation can exhibit unique catalytic properties.

Purpose of the Study:

  • To simulate the complete reshaping process of platinum nanoparticles in a carbon monoxide environment at the atomic scale.
  • To identify and characterize novel active sites formed during dynamic reshaping.
  • To understand the influence of these dynamic structures on catalytic activity for CO oxidation.

Main Methods:

  • Development of an atomistic kinetic Monte Carlo model.
  • Simulation of platinum nanoparticle reshaping in a CO environment.
  • Analysis of in situ formation and interconversion of atomic clusters on nanoparticle surfaces.

Main Results:

  • Revealed the in situ formation of atomic clusters on platinum nanoparticle surfaces, acting as new types of active sites.
  • Observed the dynamic equilibrium and interconversion between highly active 'peninsula' and inactive 'island' clusters on (111) facets.
  • Demonstrated that these dynamic structures significantly influence catalytic activity in CO oxidation.

Conclusions:

  • The study provides fundamental insights into the dynamic reshaping of nanocatalysts at the atomic level.
  • Identified novel, dynamic active sites beyond conventional understanding, boosting catalytic performance.
  • Offers guidance for the rational design of advanced nanocatalysts with enhanced reactivity.
