Size-dependent amorphous-crystalline phase transitions in ultrasmall gold colloids

VRVinavadini RamnarainMMMaxime MoreaudRMRomain Moreau

Key Points

  • The study aims to investigate how size affects the phase transitions of ultra-small gold nanoparticles.
  • Utilized aberration-corrected high-resolution transmission electron microscopy
  • Analyzed the atomic-scale mechanisms in gold colloids
  • Examined the structural changes during phase transitions
  • Identified specific size thresholds for amorphous-crystalline transitions
  • Observed distinct structural properties in nanoparticles based on size
  • Revealed implications for enhanced catalytic properties in tailored nanoparticle synthesis

Abstract

Understanding the atomic-scale mechanisms governing the structural evolution of ultra-small metal nanoparticles (NPs) is critical for controlling their synthesis and properties in catalysis and nanomedicine. Using aberration-corrected high-resolution transmission electron...
