Summary

The atomic structure of gold nanoparticles on TiO2 surfaces depends on nanoparticle size. Smaller nanoparticles form coherent interfaces, while larger ones lose coherency due to lattice mismatch.

Gold nanoparticles smaller than a few nanometers form epitaxial and coherent heterointerfaces with TiO2.
Larger gold nanoparticles exhibit a loss of lattice coherency at the interface to accommodate lattice mismatch.
Specific attachment sites on the TiO2 surface are preferentially occupied by gold atoms in small nanoparticles.

Conclusions:

Nanoparticle size dictates the structural characteristics of the gold-TiO2 interface.
Interface coherency is maintained for small nanoparticles, enabling ordered structures.
Lattice mismatch becomes a dominant factor for larger nanoparticles, leading to disordered interfaces.
