The role of Au-Cl adlayers in the Turkevich synthesis of gold nanoparticles
Abstract
Real-time surface-enhanced Raman spectroscopy reveals that Au-Cl adlayers modulate the surface chemistry of gold nanoparticles during Turkevich synthesis. The formation, evolution, and collapse of this adlayer account for the characteristic optical, electrochemical, and size changes observed during growth and termination, offering a unified chemical picture of gold nanoparticle synthesis.
