In this work, recent research progresses in the formation of PtCu nanoparticles onto the surface of graphene are described, and the obtained results are contrasted with previously published theoretical studies. To form these nanoparticles, tetrabutylammonium hexachloroplatinate, and copper acetylacetonate are used as platinum and copper precursors, respectively. Oleylamine is used as a reductor and a solvent.

- A systematic study of (PtCu) clusters ranging from size 1 to 9 was conducted using advanced computational techniques to understand their stability and growth patterns.
- The research involved optimizing various structures and analyzing characteristics like bond lengths, spin multiplicities, and stability based on molecular dynamics simulations at different temperatures.
- Key findings include the preference of copper atoms to cluster together and the formation of octahedral shapes for clusters of size 4 to 9, along with trends in dissociation energies, ionization potential, and electron affinity related to the increasing size of the clusters.
